I'm looking for something like
@@ that will work in normal mode for repeating the last Ex-mode command.
As per the rule of the XY problem, I'll also state the broader goal:
I have a fancy regex search and replace command in Ex-mode that I want to apply to almost all matches in the file. But I need to review each one before I change it. If I could use
. to repeat an Ex-mode command, I could just use
. to do what I need.
So any way to apply my search and replace to all lines interactively would help me—but I'd still be interested in an answer to the title question.
