Thank you very much for this very interesting post, both the OP as well as all others contributing and feeding the discussion.

I have one question though, what is the difference (technically, in terms of performance, logic, etc...) between:

a) Having both keys in different steps;
b) Having both keys in the same step as additional actions?

Aren't they still being "spammed" the same way by the hotkey we chose?

Thanking you in advance and have a good day,
A.
