I am sure there must be better ways but if you press Esc, then Delete (or
backspace), then ctrl + z
it will work

I found out to insert a comment I press Alt-I-M (the "m" is underlined in the

The "o" is underlined in "show/hide comments" but this keystroke combo
doesn't close the comment.

Any ideas?
