Also, don't close Vim by clicking the [X] button at top right (in the
OS-provided window decorations). Using one of the following gives you
more control:
:qa! " close Vim and discard all changes
:qa " close Vim, but not if there are changes
:xa " close Vim and save all changes
(where q stands for "quit", x stands for "exit", and a stands for "all")
The latter one will also error out if there exists a modified file
which cannot be saved, usually because it hasn't yet been named. So if
you keep one or more temporary unnamed buffer(s) with, let's say,
stuff input by means of digraphs, keymaps, etc. in order to feed it to
another program by means of the clipboard (typical temporary stuff for
me), that Vim won't be "accidentally killed": you'll have to either
use :qa! with bang (and better triple-check what you are closing
before you use that one, because it cannot be undone), or close that
particular temporary buffer with :q! (which closes nothing else,
except possibly a help buffer if these are the only two windows left,
and when you use that command you see the file being closed, it is in
the current window).

Best regards,
Tony.
