Edit outgoing keystroke

Is it possible to insert, delete the Key stroke action in the outgoing without having to re program from scratch?
I have commands that span up to eight outgoing key strokes at a time. Recently, I found a bug in my combo, and the key stroke combo would just need an additional key at the beginning.

Hi Peter,
sorry to say, currently this is not possible. We have it in our feature request list though...

The Keystroke editor is very different from usual text fields, because it lets you enter KEYS and not characters/letters.
