How can I remap the volume buttons for custom use?

Question

First of all, I only want to disable the standard volume buttons - I do not want to disable the buttons to change brightness, launchpad...

I need this because I want those buttons to trigger scripts for finer volume adjustment using FastScripts.

Answer 1

KeyRemap4MacBook

allows to intercept the keyplay.

1. Assign your scripts for fine volume adjustment to F11 and F12 (actually it's a combination of fn+vol. up/vol. down).

2. Download and install the software. Your computer will restart.

3. Open the preferences via the menu icon System Preferences → Other → KeyRemap4MacBook

4. In the Tab Change Key select the options:

   • Volume Down to F11
   • Volume Up to F12
   • F11 to Volume Down
   • F12 to Volume Up

   This will switch the behavior of the function keys with the volume keys: Now you can use fine volume adjustment with one touch and the usual volume adjustment using
   fn+vol. up/vol. down.
