If you *really* only want to control *a single* application, you can do this by:

1) Creating the respective keystroke actions at Behaviour Construction Kit > Action Factory.

2) Checking the "globally available" checkbox for the actions you created.

(please see the Help's How-To section for more step by step instructions on 1+2, if needed)

3) Go to Prefs > Mapping > Global mapping and assign your actions to the buttons of your choice (your actions are available under the "Miscellaneous" category in the popup). To turn off the Remote Buddy menu, be sure to remove the mapping of the Menu button to "Open Remote Buddy menu".
