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

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.
