thanks for asking.

You can - with limitations - use your Bluetooth keyboard to control 
Remote Buddy. Please have a look in

Preferences > Hotkey Remote > Options

to see all the default key combinations. You can modify those to use 
different keys. But be careful, since those are merely hotkeys and 
some actions in Remote Buddy need to send key events to applications 
as well, it's easy to tap into an infinite loop that goes like this:

- Hotkey press 
=> triggers Remote Buddy action 
=> triggers virtual keypress 
=> overrides hotkey press in the system 
=> hotkey press release is no longer sent by the system 
=> Remote Buddy never gets notified about the end of the event, thus 
keeps performing the action forever

This can't happen with a remote control, so it should definately be 
preferred over the virtual, hotkey-driven "Hotkey Remote".

Best regards,
