Well, there is
; to repeat the last move in some cases.
There is the
. to repeat last change.
But if I just did
@a, is there a way to repeat it? I guess such a mechanism should ignore plain movements.
for example, I have a mapping such that H does
o<ESC>D, or new line.
If I do
. , it only repeats the
D. So, to do so just for defined mappings would be a start.
I am almost certain that there is no way out of the box.
