What does capital W do in VIM?
Solution 1:
As others have said, :W
isn't defined in vanilla vim (7.0 here), so it sounds like some plugin you've installed has added it.
:command W
will tell you what it does.
Solution 2:
I guess you have a common mapping for :W
in your .vimrc
to save the file as typing :w
does. Often people press too long the shift key for the colon and make the typo but actually wanting to type :w
. You've possibly got this mapping by copy and paste of snippets into your vimrc or by using a pre-configured vim setup such as spf13-vim distribution.
.vimrc:
command! W write
However, as pointed out by Sam Stokes checking the meaning of commands via
:command W
and for keycombos:
:verbose map < C-j>
is a general approach to find out what a command or keycombo does.
Solution 3:
You can test this line
{Cursor}It's the test
{Cursor} : Cursor position in normal mode, w: will move word which separated by " ,./?" W: will move word which separated by " " only
