Firefox 57, also known as Firefox Quantum, will be released on November 14. It will bring some significant changes to the Firefox rendering engine to improve performance and open the door for more new features in the future. Here is what you need to know if you are a user of the NVDA screen reader. Continue reading “Firefox 57 from an NVDA user’s perspective”
OK folks, this is hopefully it, the ultimate way to map the CapsLock key of your MacBook to be used as a NVDA or JAWS modifier key in a virtual machine running Windows.
The MacBook’s keyboard has no insert key. The insert key, however, is the main modifier key used by screen readers on Windows. This stems from the era where computers all still had big keyboards with number pads, and even laptops were still big enough that most of them had these.
In newer, tinier models, these have gone for good. Yes, there are possibilities to use external Bluetooth number pads, but hey, this is not really mobile, is it? 😉 These keyboards do, however, still have CapsLock keys. So why not use them? If you then switch your Windows screen reader to laptop layout, you get full functionality within a Windows VM.
I realize there are other solutions out there to re-map another key to the insert key within Windows by using tools such as SharpKeys. But I found these always conflicted with other keys, caused whacky behavior if VoiceOver was running on the Mac side still, etc. etc. So I was always on the look-out for a better solution.
Credit where credit is due
And heureka! I found it in a German FAQ article on TuKSuB. Thank you, Kamil, for putting this together! This article is based on, but not an exact translation of, Kamil’s entry. So here we go!
For this to work, we need two freely available Mac tools: Karabiner (formerly KeyRemap4MacBook), and Seil (formerly PCKeyboardHack). Karabiner will map the CapsLock key to a VoiceOver key for us, and Seil will help us to use CapsLock as an Insert key in a Windows VM. Go ahead and download and install both tools now. They come with standard installation packages. We’ll use each tool in the following steps. Just make sure you install the right version for your operating system. Seil, for example, comes in different versions for OS X 10.11 El Capitan and 10.10 Yosemite plus 10.9 Mavericks.
Step 1: Remap CapsLock to a VoiceOver key
- Go to your Applications folder (Cmd+Shift+A), and launch Karabiner. On first launch, you will most likely be prompted that KarabinerAxHelper wants to use Accessibility features.
- Click the Open Preferences button, which will open to the Security/Privacy tab. Unlock the settings with your admin password, and enable the checkbox for KarabinerAxHelper in the Accessibility permissions table. Now, close System Preferences with Cmd+W.
- Press VoiceOver+M twice to reach the notifications area at the top right of your Mac screen. Karabiner inserted itself here. Use VoiceOver+Right and Left Arrows to find Karabiner and press VoiceOver+SpaceBar to activate. DownArrow to Preferences and activate again with VoiceOver+SpaceBar or Enter.
- The Preferences window opens to the Change Key tab. VoiceOver+RightArrow until you find the Remap Keys table.
- DownArrow in this table until you reach the row that reads „For blind users“. Press RightArrow to open that node.
- DownArrow once, and activate the checkbox for the now visible option „Use CapsLock as VoiceOver key“. The rest of that checkbox label gives a hint to what’s to be done for virtual machines, too, and we’ll get to that in a minute.
- Press Cmd+W to close this window.
Step 2: Change CapsLock key behavior in System Preferences
Now, we need to tell Mac OS X to leave the CapsLock key alone.
- Open the menu bar with VoiceOver+M, and DownArrow on the Apple menu to System Preferences.
- Tab to Keyboard and press VoiceOver+SpaceBar to open that settings panel.
- Make sure the Keyboard tab is selected, and at the bottom of the screen, find the Modifiers button and press it with VoiceOver+SpaceBar.
- In the Modifiers dialog, VoiceOver+RightArrow to the CapsLock popup menu, press VoiceOver+SpaceBar and select the option No Action. Press Enter to make the choice.
- VoiceOver+RightArrow onto the OK button and press it.
- Close the System Preferences with Cmd+W.
Step 3: Using CapsLock as the Insert key on Windows
Now, the last step is to use the Seil tool to map CapsLock to the Insert key when a virtual machine is running. Karabiner already hinted for us to do this when we checked the option to use CapsLock as a VoiceOver key above.
- From your Applications folder, launch the Seil application.
- Make sure the Setting tab is selected. Find the first table. In my case, it has 6 entries.
- DownArrow to find the Change the CapsLock Key option, and expand it by pressing RightArrow.
- DownArrow once more to a similar entry called Change the CapsLock key. Interact with the row and find the checkbox. Press VoiceOver+Space to check it.
- VoiceOver+RightArrow onto the column called KeyCode, and press VoiceOver+SpaceBar to edit this value.
- Change it to 110 from the default of 51, and press Enter to accept.
- Close the window with Cmd+W.
Step 4 only for El Capitan: Disable CAPS Lock as VoiceOver modifier in VoiceOver Utility
- Launch VoiceOver Utility by pressing Control+Option+F8 while VoiceOver is running.
- In the General category, change the popup for the VoiceOver modifier from “Ctrl+Option or CAPS Lock” to “Only Ctrl+Option”. This is new in 10.11 El Capitan, and VoiceOver sets the modifier to be both by default.
- Quit VoiceOver Utility.
If you don’t change this, the CAPS Lock key will cause erratic behavior when used inside virtual machines.
Step 5: Launch your virtual machine and test
In order to verify that this all worked, launch VMware Fusion or your virtualization software of choice, and launch your Windows VM. Verify that NVDA, JAWS or your other preferred screen reader can now use the CapsLock key. JAWS should immediately find it, and in my case, NVDA did, too. Note that you should not tell your screen reader to use CapsLock as a modifier key, but leave it on Insert instead. But you can use the laptop keyboard layout for better access to many commands.
This post is no longer current. For an update on the reasons why, read this post. The below post is kept for historic reasons, since they reflect my thoughts and reasoning from that time.
Yes, you read correctly! After five years on a Mac as my private machine, I am switching back to a Windows machine in a week or so, depending on when Lenovo’s shipment arrives.
You are probably asking yourself, why I am switching back. In this post, I’ll try to give some answers to that question, explain my very personal views on the matters that prompted this switch, and give you a bit of an insight into how I work and why OS X and VoiceOver no longer really fit that bill for me.
A bit of history
When I started playing with a Mac in 2008, I immediately realised the potential this approach that Apple was taking had. Bundling a screen reader with the operating system had been done before, on the GNOME desktop, for example, but Apple’s advantage is that they control the hardware and software back to front and always know what’s inside their boxes. So a blind user is always guaranteed to get a talking Mac when they buy one.
On Windows and Linux, the problem is that the hardware used is unknown to the operating system. On pre-installed systems, this is usually being taken care of, but on custom-built machines with standard OEM versions of Windows or your Linux distro downloaded from the web, things are different. There may be this shiny new sound card that just came out, which your dealer put in the box, but which neither operating system knows about, because there are no drivers. And gone is the dream of a talking installation! So, even when Windows 8 now allows Narrator to be turned on very early in the installation process in multiple languages even, and Orca can be activated early in a GNOME installation, this all is of no use if the sound card cannot be detected and the speech synthesizer canot output its data through conected speakers.
And VoiceOver had quite some features already when I tried it in OS X 10.5 Leopard: It had web support, e-mail was working, braille displays, too, the Calendar was one of the most accessible on any desktop computer I had ever seen, including Outlook’s calendar with the various screen readers on Windows, one of which I had even worked on myself in earlier years, and some third-party apps were working, too. In fact, my very first Twitter client ran on the Mac, and it was mainstream.
There was a bit of a learning curve, though. VoiceOver’s model of interacting with things is quite different from what one might be used to on Windows at times. Especially interacting with container items such as tables, text areas, a web page and other high-level elements can be confusing at first. If you are not familiar with VoiceOver, interacting means zooming into an element. A table suddenly gets rows and columns, a table row gets multiple cells, and each cell gets details of the contained text when interacting with each of these items consecutively.
In 2009, Apple advanced things even further when they published Snow Leopard (OS X 10.6). VoiceOver now had support for the trackpads of modern MacBooks, and when the Magic TrackPad came out later, it also just worked. The Item Chooser, VoiceOver’s equivalent of a list of links or headings, included more items to list by, and there was now support for so-called web spots, both user-defined and automatic. A feature VoiceOver calls Commanders allowed the assignment of commands to various types of keystrokes, gestures, and others. If you remember: Snow Leopard cost 29 us Dollars, and aside from a ton of new features in VoiceOver, it obviously brought all the great new features that Snow Leopard had in store for everyone. A common saying was: Other screen readers needed 3 versions for this many features and would have charged several hundred dollars of update fees. And it was a correct assessment!
In 2011, OS X 10.7 Lion came out, bringing a ton of features for international users. Voices well-known from iOS were also made available in desktop formats for over 40 languages, international braille tables were added, and it was no longer required to purchase international voices separately from vendors such as AssistiveWare.. This meant that users in more countries could just try out VoiceOver on any Mac in an Apple retail store or a reseller’s place. There were more features such as support for WAI-ARIA landmarks on the web, activities, which are either application or situation-specific sets of VoiceOver settings, and better support for the Calendar, which got a redesign in this update.
First signs of trouble
But this was also the time when first signs of problems came up. Some things just felt unfinished. For example: The international braille support included grade 2 for several languages, including my mother tongue German. German grade 2 has a thing where by default, nothing is capitalized. German capitalizes many more words than English, for example, and it was agreed a long time ago that only special abbreviations and expressions should be capitalized. Only in learning material, general orthographic capitalization rules should be used. In other screen readers, capitalization can be turned on or off for German and other language grade 2 (or even grade 1). Not so in VoiceOver for both OS X and iOS. One is forced to use capitalization. This makes reading quite awkward. And yes, makes, because this remains an issue in both products to this date. I even entered a bug into Apple’s bug tracker for this, but it was shelved at some point without me being notified.
Some other problems with braille also started to surface. For some inexplicable reason, I often have to press routing buttons twice until the cursor appears at the spot I want it to when editing documents. While you can edit braille verbosity where you can define what pieces of information are being shown for a given control type, you cannot edit what gets displayed as the control type text. A “closed disclosure triangle” always gets shown as such, same as an opened one. On a 14 cell display, this takes two full-length displays, on a 40 cell one, it wastes most of the real estate and barely leaves room for other things.
Other problems also gave a feeling of unfinished business. The WAI-ARIA landmark announcement, working so well on iOS, was very cumbersome to listen to on OS X. The Vocalizer voices used for international versions had a chipmunk effect that was never corrected and, while funny at first, turned out to be very annoying in day-to-day use.
OK, the enthusiastic Mac fan boy that I was, thought, let’s report these issues and also wait for the updates to trickle in. None of the 10.7 updates really fixed the issues I was having.
Then a year later, Mountain Lion, AKA OS X 10.8, came out, bringing a few more features, but compared to the versions before, much much less. Granted, it was only a year between these two releases, whereas the two cycles before had been two years each, but the features that did come in weren’t too exciting. There was a bit polish here and there with drag and drop, one could now sort the columns of a table, and press and hold buttons, and a few little things more. Safari learned a lot new HTML5 and more WAI-ARIA and was less busy, but that was about it. Oh yes and one could now access all items in the upper right corner of the screen. But again, not many of the previously reported problems were solved, except for the chipmunk effect.
There were also signs of real problems. I have a Handy Tech Evolution braille display as a desktop braille display, and that had serious problems from one Mountain Lion update to the next, making it unusable with the software. It took two or three updates, distributed over four or five months, before that was solved, basically turning the display into a useless piece of space-waster.
And so it went on
And 10.9 AKA Mavericks again only brought a bit polish, but also introduced some serious new bugs. My Handy Tech BrailleStar 40, a laptop braille display, is no longer working at all. It simply isn’t being recognized when plugged into the USB port. Handy Tech are aware of the problem, so I read, but since Apple is in control of the Mac braille display drivers, who knows when a fix will come, if at all in a 10.9 update. And again, old bugs have not been fixed. And new ones have been introduced, too.
Mail, for example, is quite cumbersome in conversation view now. While 10.7 and 10.8 very at least consistent in displaying multiple items in a table-like structure, 10.9 simply puts the whole mail in as an embedded character you have to interact with to get at the details. It also never keeps its place, always jumping to the left-most item, the newest message in the thread.
The Calendar has taken quite a turn for the worse, being much more cumbersome to use than in previous versions. The Calendar UI seems to be a subject of constant change anyway, according to comments from sighted people, and although it is technically accessible, it is no longer really usable, because there are so many layers and sometimes unpredictable focus jumps and interaction oddities.
However, having said that, an accessible calendar is one thing I am truly going to miss when I switch back to Windows. I know various screen readers take stabs at making the Outlook calendar accessible, and it gets broken very frequently, too. At least the one on OS X is accessible. I will primarily be doing calendaring from my iOS devices in the future. There, I have full control over things in a hassle-free manner.
iBooks, a new addition to the product, is a total accessibility disaster with almost all buttons unlabeled, and the interface being slow as anything. Even the update issued shortly after the initial Mavericks release didn’t solve any of those problems, and neither did the 10.9.1 update that came out a few days before Christmas 2013.
From what I hear, Activities seem to be pretty broken in this release, too. I don’t use them myself, but heard that a friend’s activities all stopped working, triggers didn’t fire, and even setting them up fresh didn’t help.
Here comes the meat
And here is the first of my reasons why I am switching back to Windows: All of the above simply added up to a point where I lost confidence in Apple still being dedicated to VoiceOver on the Mac as they were a few years ago. Old bugs aren’t being fixed, new ones introduced and, despite the beta testers, which I was one of, reporting them, were often not addressed (like the Mail and Calendar problems, or iBooks). Oh yes, Pages, after four years, finally became more accessible recently, Keynote can now run presentations with VoiceOver, but these points still don’t negate the fact that VoiceOver itself is not receiving the attention any more that it would need to as an integrated part of the operating system.
The next point is one that has already been debated quite passionately on various forums and blogs in the past: VoiceOver is much less efficient when browsing the web than screen readers on Windows are. Going from element to element is not really snappy, jumping to headings or form fields often has a delay, depending on the size and complexity of a page, and the way Apple chose to design their modes requires too much thinking on the user’s part. There is single letter quick navigation, but you have to turn on quick navigation with the cursor keys first, and enable the one letter quick navigation separately once in the VoiceOver utility. When cursor key quick navigation is on, you only navigate via left and right arrow keys sequentially, not top to bottom as web content, which is still document-based for the most part, would suggest. The last used quick navigation key also influences the item chooser menu. So if I moved to a form field last via quick navigation, but then want to choose a link from the item chooser, the item chooser opens to the form fields first. I have to left arrow to get to the links. Same with headings. For me, that is a real slow-down.
Also, VoiceOver is not good at keeping its place within a web page. As with all elements, once interaction stops, then starts again, VoiceOver starts interaction at the very first element. Conversations in Adium or Skype, and even the Messages app supplied by Apple, all suffer from this. One cannot jump into and out of the HTML area without losing one’s place. Virtual cursors on Windows in various screen readers are very good at remembering the spot they were at when focus left the area. And even Apple’s VoiceOver keystroke to jump to related elements, which is supposed to jump between the input and HTML area in such conversation windows, is a subject of constant breakage, re-fixing, and other unpredictability. It does not even work right in Apple’s own Messages app in most cases.
Over-all, there are lots of other little things when browsing the web which add up to make me feel I am much less productive when browsing the web on a Mac than I am on Windows.
Next is VoiceOver’s paradigm of having to interact with many elements. One item where this also comes into play is text. If I want to read something in detail, be it on the web, a file name, or basically anything, I have to interact with the element, or elements, before I get to the text level, read word by word or character by character, and then stop interaction as many times as I started it to get back to where I was before wanting to read in detail. Oh yes, there are commands to read and spell by character, word, and sentence, but because VoiceOver uses the Control+Option keys as its modifiers, and the letters for those actions are all located on the left-hand side of the keyboard, it means I have to take my right hand off its usual position to press these keys while the left hand holds the Control and Option keys. MacBooks as well as the Apple Wireless Keyboard don’t have Control and Option keys on both sides, and my hand cannot be bent in a fashion that I can grab these keys all with one hand. Turning on and off the VoiceOver key lock mechanism for this would add even more cumbersome to the situation.
And this paradigm of interaction is also applied to the exploration of screen content by TrackPad. You have to interact or stop interacting with items constantly to get a feel for the whole screen. And even then, I often feel I never get a complete picture. Unlike on iOS, where I always have a full view of a screen. Granted, a desktop screen displays far more information than could possibly fit on a TrackPad without being useless millimeter touch targets, but still the hassle of interaction led to me not using the TrackPad at all except for some very seldom specific use cases. We’re talking about a handful instances per year.
Next problem I am seeing quite often is the interaction braille gives me. In some cases, the output is just a dump of what speech is telling me. In other cases, it is a semi-spacial representation of the screen content. In yet another instance, it may be a label with some chopped off text to the right, or to the left, with the cursor not always in predictable positions. I already mentioned the useless grade 2 in German, and the fact that I often have to press the routing button at least twice before the cursor gets where I want it to go. The braille implementation in VoiceOver gives a very inconsistent impression, and feels unfinished, or done by someone who is not a braille reader and doesn’t really know the braille reader’s needs.
Next problem: Word processing. Oh yes, Pages can do tables in documents now, and other stuff also became more accessible, but again because of the paradigms VoiceOver uses, getting actual work done is far more cumbersome than on Windows. One has, for example, to remember to decouple the VoiceOver cursor from the actual system focus and leave that inside the document area when one wants to execute something on a tool bar. Otherwise, focus shifts, too, and a selection one may have made gets removed, rendering the whole endeavor pointless. Oh yes, and one has to turn the coupling back on later, or habits will result in unpredictable results because the system focus didn’t move where one would have expected it to. And again, VoiceOver’s horizontally centered navigation paradigm. Pages of a document in either Pages or Nisus Writer Pro appear side by side, when they are visually probably appearing below one another. Each page is its own container element. All of this leaves me with the impression that I don’t have as much control over my word processing as I have in MS Word or even the current snapshot builds of OpenOffice or LibreOffice on Windows. I also get much more information that I don’t have to look for explicitly, for example the number of the current page. NVDA, but probably others, too, have multilingual document support in Word. I immediately hear which spell checking is being used in a particular paragraph or even sentence.
There are some more issues which were not addressed to this day. There is no PDF reader I know of on OS X that can deal with tagged (accessible) PDFs. Even when tags are present, Preview doesn’t do anything with them, giving the more or less accurate text extraction that one gets from untagged PDFs. As a result, there is no heading navigation, no table semantic output, and more that accessible PDFs support.
And the fact that there is no accessible Flash plug-in for web browsers on OS X also has caused me to switch to a Windows VM quite often just to be able to view videos embedded in blogs or articles. Oh yeah, HTML5 video is slowly coming into more sites, but the reality is that Flash is probably still going to be there for a couple of years. This is not Apple’s fault, the blame here is solely to be put on Adobe for not providing an accessible Flash plug-in, but it is one more thing that adds to me not being as productive on a Mac as I want to be on a desktop computer.
In summary: By all of the above, I do not mean to say that Apple did a bad job with VoiceOver to begin with. On the contrary: Especially with iOS, they have done an incredibly good job for accessibility in the past few years. And the fact that you can nowadays buy a Mac and install and configure it fully in your language is highly commendable, too! I will definitely miss the ability to configure my system alone, without sighted assistance, should I need to reinstall Windows. As I said above, that is still not fully possible without assistance. It is just the adding up of things that I found over the years that caused me to realize that some of the design decisions Apple has made for OS X, bugs that were not addressed or things get broken and not fixed, and the fact that apps are either accessible or they aren’t, and there’s hardly any in-between, are not compatible with my way of working with a desktop computer or laptop in the longer term. For iOS, I have a feeling Apple are still full-steam ahead with accessibility, introducing great new features with each release, and hopefully also fixing braille problems as discussed by Jonathan Mosen in this great blog post. For OS X, I am no longer as convinced their heart is in it. As I have a feeling OS X itself may become a second-class citizen behind iOS soon, but that, again, is only my personal opinion.
So there you have it. This is why I am going to be using a Lenovo notebook with NVDA as my primary screen reader for my private use from now on. I will still be using a Mac for work of course, but for my personal use, the Mac is being replaced. I want to be fast, effective, productive, and be sure my assistive technology doesn’t suddenly stop working with my braille display or be susceptible to business decisions placing less emphasis on it. Screen readers on Windows are being made by independent companies or organizations with their own business models. And there is choice. If one does no longer fit particular needs, another will most likely do the trick. I do not have that on OS X.
