Program to re-assign keyboard commands?

[madmaxmedia]

Hi,

Is there a program that will allow me to take a keyboard command (say command <) in a program, and map it to another keyboard command (say command arrow)?

I am using Circus Ponies Notebook, and the keyboard shortcut to expand/ collapse an outline is very unintuitive. I want to assign command-arrow key to do the same thing (but only for this program.)

I don't need to eliminate the first keyboard command, I just want another key combination to duplicate an existing command.

Thanks,
Steve
