What would be great is if there was a token that could be in the Macro name to allow the Return key to be its trigger in a Conflict Palette.
Putting a space before the name works for the spacebar to be the trigger. But at the moment putting in front of the Macro name doesn't make the Return Key the trigger. (I just tried it in case it might have worked )
The only way I have managed to get Return to always trigger a specific Macro in a Conflict Palette is to give it a name of one Letter and make sure all the other Macros with the same Shortcut Key have names starting with the same letter. This works but it would be nice if I could call the Macro "Keyboard Maestro" rather than "K" and still be sure the Return key will select it from a Conflict Palette.
