How can I make presets of resolution

Currently the fn-f4 (monitor toggle) sets the X desktop to a large size and then moving the cursor to far corners moves the desktop around. I would like to simply have my internal LCD and external CRT monitors to go into clone mode. A resolution that both the monitor and the computer can agree upon.

Mode 1 - LCD at 1280x800 [DEFAULT]
Mode 2 - LCD at 1024x768, VGA at 1024x768 [CLONED MODE]

Going into nvidia-settings, the panning is by default 1280x800 when I would like both monitors and the X desktop to be 1024x768 in Mode 2.

The nvidia-settings Basic/Advanced button allows you to change the panning to 1024x768, which is a workaround, but I wouldn't expect my mother to know how to do this. Assistance is requested in understanding how I can go about making two preset modes and cycling though them, either as a script or by re-scrpting the toggle monitor key (whichever is possible). I have tried Xrandr, but I don't think it works properly with the nVidia binary driver.

$ xrandr
