Keybindings for the Magnifier

[Robert Cole <rkcole72984 gmail com>]

Hello there!

I am curious as to whether or not it is possible to set the magnifier's 
keybindings (turn on/off, zoom in/out) by setting keys via the command 
line. I ask this because if this is possible, it would make things a lot 
more convenient in using a live system (at least in my case) as I tend 
to work on PCs (troubleshooting and data recovery) using live Lnux 
distros (and I sometimes require magnification to do this). If this can 
be done then I could write a simple shell script which I could use to 
set these bindings. Right now, each time I boot into a live system, I go 
into System Settings (GNOME Control Center) and manually set the 
keybindings under the Universal Access section of the Shortcuts tab in 
the Keyboard settings dialog.

Is it at all possible to set these bindings via the command line? If so, 
how would I go about doing this?

Thank you very much for any input on this topic!

Take care.
