Yes, but it can be dangerous in that it's possible to put the system 
into an unstable state.  Using the System Settings is the safe way to do 
this.  Nevertheless, by first using the GUI, it is possible to do what 
you want from the command line.  Use the following approach.

First, use the control centre Keyboard setting dialog to choose 
keystrokes for the magnifier on/off, zoom-in, and zoom-out functions. 
For example, suppose the zoom-in keystroke is set to "Ctrl+2" in the 
"Shortcuts/Universal Access" dialog.  Then, on the command line, use the 
'gsettings' command to determine the string value of the keystroke:

$ gsettings get org.gnome.settings-daemon.plugins.media-keys 
magnifier-zoom-in

You should see the following as a response:
'<Primary>2'

Use the same technique for on/off and zoom out -- first set them using 
the control centre dialog, then find out their value strings:

$ gsettings get org.gnome.settings-daemon.plugins.media-keys magnifier
$ gsettings get org.gnome.settings-daemon.plugins.media-keys 
magnifier-zoom-out

Once you have valid value strings you can use them with gsettings 'set' 
command.  For example:

$ gsettings set org.gnome.settings-daemon.plugins.media-keys 
magnifier-zoom-in '<Primary>2'

Hope that helps.
