x11 + hot keys = annoying

[spooner1887]

Hello,

I'm was wondering if there is a way to set the hot keys for X11. I am currently debugging a parallel program with gdb and I am doing it in X11. I have the box "Follow system keyboard layout" checked in X11 preferences.

I would like to do several things in X11 that I can do in the terminal.

command + right/left arrow : switch between open windows
command + t : open new tab

Also I'm not clear where in System Preferences these hot keys are set for the Terminal or X11. Not being able to quickly switch between open instances of X11 is driving me nuts. Thanks!
