Do I need always type a char then <BS>? Is there a better solution? I wander whether the vim option can do this automatically.
The idea of the comment shown above was to leave something to remind you that you had to come back later, since, as you said, you want to leave the indent there "for future use"; also, the comment would be sure to stay in place even if the "bare indent" didn't. But if just adding, let's say, a period, then backspacing over it, makes the indent remain, then you don't have to type a lengthy comment unless you need it. You may even try (untested) :inoremap <CR> <CR>.<BS> Note: Next time, please use "Reply to all" rather than "Reply to sender", unless you're straying off-topic. Best regards, Tony.
