I don't "normally" use it. I've just seen it in a clever mapping (from
Dr. Chip I think) to reverse a line, and I just attempted to use it in
the following situation:
I had a comment line that was aligned right within the comment, like
this:
/****************************** Object Definitions */
I wanted to change it to:
/*************************** Function Declarations */
Where the length of the line is preserved.
I thought the fastest way would be to go into replace mode at the end
of the comment and type the words backwards, with 'revins' set.
But 'revins' does not apply in replace mode for some reason.
No big deal, just an unexpected quirk that I figure might be simple to
change. Then again, this would be something that could easily break a
lot of plugins, if they use insert mode, because there would suddenly
be another option they need to check and/or restore.
