Hello, Aurelian.
To be honest, I use magnification for things like reading
documents in Evince as well as to spot check things (e.g. document
layout when creating Web pages or documents in LibreOffice). I
have never actually used text tracking at all (even when I used
Windows); I have mainly always used magnification for reading.
When it comes to typing e-mails and mainly just any sort of typing
which I do I use Orca. I am trying to rely more on Orca nowadays
rather than on magnification because my good eye seems to become
strained much more easily than it used to. One other reason which
I could not use text tracking is that I have to have my good eye
literally an inch or so away from the screen (if not less) to be
able to use magnification. Unfortunately, not all applications are
accessible to Orca, and so for those applications I use
magnification. I by no means put any blame on Orca developers for
this because Joanie and other Orca developers should not have to
make Orca work with other applications; this could be very
cumbersome when updates to these different applications arise.
Ideally, developers could just add in some code to make
applications more accessible to Orca, but I'll get off that rant
as this is not the Orca list, and this topic is concerning
magnification. <smile> Sorry about that. I am not saying any
of this with any ill intent, but rather in the hope which I have
of seeing Linux become a COMPLETELY accessible platform for users
so that people with disabilities can easily use a free platform to
be productive on their computer systems.
I hope that all is well, and have a great day!

Hi, Robert and list,
These are the shortcuts I use:
Compiz:
- Windows key + scroll wheel to zoom in/out.
- Windows key + arrow keys to pan image.
GNOME Shell:
- Windows key + Keypad Enter to turn zoom on/off
- Windows key + Keypad Plus and Minus to zoom in/out.
These do not conflict with any other shortcuts. Basically, my
Windows key is my "zoom" key.
Robert, how do you manage to have the magnifier follow your text
insertion? Do you use the pan function in Compiz or just move your
mouse? The lack of "follow text insertion" functionality prevents
me from using Linux on a regular basis. I have to stick to Windows
and the built-in magnifier which works flawlessly for me (I don't
need the fancy features of expensive commercial zoomers).
Take care.

Hello, Joseph, and thanks for your reply.
I am sorry for my delayed response.
Doing something like SHIFT+Scroll Up to Zoom In and
SHIFT+Scroll Down to Zoom Out would be a great idea, if
possible. I have seen magnification software which only makes
use of the scroll wheel for zooming, but this makes it
difficult (and sometimes impossible) to scroll when reading
documents because the zoom function would be invoked in the
magnification software. Even CTRL+Scroll Up/Down could cause
conflicts, as some applications (such as Firefox and Evince)
use the CTRL+Scroll Up/Down combination for their own zoom
features. I personally do not use the built-in zooming
features in applications such as Firefox or Evince; it is much
easier and it is much more efficient for me to just use
magnification and pan around the application when reading or
when doing work.
As far as keyboard shortcuts for the magnifier go, I had
originally set mine as follows:
1. Start/Stop the magnifier: CTRL+ALT+M (There do not seem to
be any conflicts with this one)
2. Zoom In: ALT+Up Arrow
3. Zoom Out: ALT+Down Arrow
The keyboard shortcuts for zooming in and for zooming out
conflicted with a predefined set of shortcuts which are used
to change the search engine in the Firefox search bar, so I
changed them to the following:
1. Zoom In: ALT+= ('=' on the number row)
2. Zoom Out: ALT+- ('-' on the number row)
These do not seem to cause any conflicts.
Thanks again for your response, Joseph. I hope you are having
an excellent day (or evening, depending on where you are
located).
Take care.

Hi Robert,
You wrote:
I was just curious as to whether or not it is possible
(or would be possible) to use the scroll wheel on my
mouse in combination with a key on my keyboard (e.g. the
Control key) to zoom in or out on the magnifier.
Anything is possible :-). And, this is a no-brainer.
I'll take a look to see if there is a feature request in
the bug data base somewhere, and, if not, raise it.
But, this has me thinking about a related issue. The
GNOME UI design team is currently working on a menu that
allows quick access to useful accessibility preferences --
things like "turn on/off magnification", "turn on/off
inverse video", "turn on/off screen reader", and so on.
They are mulling over what should be in that menu.
Controlling magnification factor using the scroll wheel
falls into this "quick access" category. Now, in this
case, it's not part of any menu; it's simply available
from one of the common UI devices (the mouse).
I ask this because many of the key bindings which I used
for Zoom in and Zoom Out are used by other programs.
In case you don't know, you can configure key bindings for
Zoom from the "Keyboard" control centre panel:
1. Go to System Settings.
2. Open the Keyboard panel.
3. Choose the Shortcuts tab.
4. Select the Universal Access item from the list on the
left.
5. Choose the preference on the right, and set the
keystroke you want (follow the direction at the bottom of
the window).
You can at least assign some key stroke to the zoom in/out
functions to avoid having to invoke the full zoom options
dialog. Hopefully they aren't too different from what you
are used to (the bindings that are use by other programs).
Hope that helps.
