I generally recommend to exit either via :xa (save all & exit) or :qa! (discard all and exit), bound to ZZ or ZA respectively. If you exit via :q or :wq, it just closes the current buffer, and moves to the next one. E.g. if you have a neotree open along with the editor, you type :wq, it closes the editor buffer and moves you into the file tree, which can be very confusing for beginners.
Are you sure? IIRC :x only writes the file again if there's a change where :w(q) always writes again (which takes longer when editing a remote file via scp://). For a non-exiting version of :x there is :up. I bound :up to <leader>fs after I learned about it. I used to have :w on the same keybind so it was a straight upgrade. Now I can just quick hit it at any time and there's no waiting around if the file hadn't changed. Saves some time and annoyances.
Yes, through ":help wqa" which lists it as such and double checking with a quick test. It doesn't write unchanged files, same as :xa instead of being an exact "all" version of :wq
:P :Print
:[range]P[rint] [count] [flags]
Just as ":print". Was apparently added to Vi for
people that keep the shift key pressed too long...
This command is not supported in Vim9 script.
Note: A user command can overrule this command.
See ex-flags for [flags].
