Add <enter> to .exrc shortcut

Question

I found this cool exrc file to make the F-Keys to things, e.g. map #2 :set number, which puts just that in that ex command thingy, and lets me press enter to confirm. However, I made one to close (map #4 :q) and I would like it if it automatically added an enter, so it just closes without me having to press enter first. Then I would just hit and it closes.

How do I add that enter character?

Answer 1

You just need to add <CR> at the end of your mapping:

map <F4> :q<CR>

See :help key-notation.
