I googled and that's what it says:
To go back a word, b is used. Once again, B will include more characters in what Vim considers a word.
I didn't understand what B does different from b. Can you give me an example to make it clear for me to understand? Thanks.
[EDIT]Actually I wonder this because in the online vim game, I tried to go back to WORDS from ! with b, but it didn't work. However when I tried it with Vim installed in my computer, it worked with b. So is this only for to make player use B with the help of clue?
Here is the picture of game:
de means "cut from here to the end of the current word". Show activity on this post. The cursor deleted the letters from the current word, until end, but without space.
l: local to a function. g: global. :help internal-variables. Follow this answer to receive notifications.
The key difference is the exclamation mark here. :q will warn you about unsaved changes and will not let you exit. :q! will not warn you.
Like most of the capitalized movement pairs, b moves by word, but B moves by WORD. The difference is that vim considers a "word" to be letters, numbers, and underscores (and you can configure this with the iskeyword
setting), but a "WORD" is always anything that isn't whitespace.
So given this:
foo-bar-baz
If your cursor is on the z
and you press b, the cursor will move back to the start of baz
, then to the hyphen, then back to the start of bar
, and so on. Each of these is a different "word" to vim: foo
, -
, bar
, -
, baz
.
But if you press B, the cursor will move all the way left to the f
, because foo-bar-baz
is all non-whitespace and thus a single WORD.
:help word
inside vim explains this too.
Regarding the vim game: I think the game treats boulders as punctuation. Try typing it in vim like this:
not WORDS*!
With the cursor on !
, b will move you back to the *
, because *!
is all punctuation and thus one word. But that *
is actually a boulder, so you can't move there, so nothing happens. B, on the other hand, will skip you back over everything that isn't a space.
B treats punctuation as part of the word, using only whitespace as word delimiters; b does not treat punctuation as part of the word.
