Is it possible to make Left Alt+A and Right Alt+A do different things? And of course, other modifier keys.

If not, maybe the following idea would work? If AppleScript, Python, Ruby, Perl etc. can detect left/right modifiers I can set complicated key bindings in sublime text (like ["cmd+ctrl+shift+alt+a", "cmd+ctrl+shift+alt+a"]) and send those keystrokes with AppleScript or Automator?


You could remap the key combinations with KeyRemap4MacBook:

<?xml version="1.0"?>
        <autogen>__KeyToKey__ KeyCode::A, ModifierFlag::OPTION_R, KeyCode::F19</autogen>

Or just change modifier keys:

<autogen>__KeyToKey__ KeyCode::OPTION_R, KeyCode::CONTROL_L, ModifierFlag::CONTROL_L | ModifierFlag::OPTION_L | ModifierFlag::SHIFT_L | ModifierFlag::COMMAND_L</autogen>

See the source for the key code values and predefined settings.
