I have recently been doing an awful lot of editing in the Keyboard Maestro Editor, and I found that CMD+K will toggle the Action Pane. However I am right handed and my right hand is busy with the mouse. So I thought, why not remap CMD+K to a key on the Left hand side of the Keyboard, then I do not have to let go of the mouse.
So I did the following
1: Created a macro group called PROD Keyboard Maestro specific
2: Set it to be only active in Keyboard Maestro (Editor)
3: Created the the new macro as “”Toggle Keyboard Maestro Actions Pane. CMD+S
( Chose CMD+S as my combination, but it is up to you).
4: Created rest of macro as per picture.
( I know I could have used Type a Keystroke CMD+K, but I prefer the menu approach here).
