Re: Keybindings for the Magnifier

[Robert Cole <rkcole72984 gmail com>]

Thank you very much for that, Joseph. That is exactly what I was looking

This will make things much easier, hopefully, rather than having to go 
into GNOME Control Center to set the keybindings each time I use a live 
system. I really appreciate you taking the time to write me back about this.

Take care.
