That might be a good suggestion, but I am not sure.

As everyone here no vi has two main states: input and command. Beside
that there are the normal Emacs key sequences states during input of
key sequences. (The clash between these states is why ESC-TAB can not
be used.)

For the "command" state the g key is unused. Using it directly would
be a waste, but a sequence beginning with g might be good.

But I am not very sure of the value of it since using it would require
switching to "command" state first. And I think you are most likely to
be in "input" mode if you want to do completion.

ESC is the only "control char" that I am using of those vi recognize
as its own. (The other are less important.)

I suggest finding a key sequence in Emacs that does not use M (Alt).
TAB by itself seems to be the favorite on EmacsWiki. Maybe use two
fast TABs for it by default. And have C-RET as backup?
