Disable ⌘+p and ⌘+s in Terminal.app I continually hit ⌘-P and ⌘-S while Terminal is in focus, due to alt-tabbing between my text editor and other programs.

Does anyone know how to disable these keys in Terminal.app?
You could try out Keymando which will let you set specific shortcuts for programs. In this case, you would set those commands to do nothing.

Another solution would be to use iTerm 2, which allows you to specify shortcuts for keys (or to ignore).
