To open a buffer in a vertical split, you can use the word "vert". For example :

:vert term  #it opens a terminal in a vertical split
:vert sb1   #it opens the buffer 1 in a vertical split

Why i can't make the vert command shorter ?

On internet, i saw that people just write :


For me it doesn't work...

The full :vert is :vertical and the full :term is :terminal. In order to save typing, Vim lets you type as few characters as possible as long as there is no ambiguity so, for :vertical, you could type:


but you can't go further because there are three commands that start with ver:


and Vim can't really be expected to guess which one you want. Therefore, :vert is the shortest you can get.

The mechanism is described in chapter 20 of the user manual: :help 20.2.

Now… those people on the internet are probably using or trying to use abbreviations, which are introduced in chapter 24 of the user manual: :help 24.7 and thoroughly documented under :help abbreviations.

  • ":sb1" here vim understands 's' as split..But ":s/foo/bar" here vim understands 's' as substitute....It drives me crazy. Would you please explain that ? Dec 9, 2022 at 15:19

    :sb is short for :sbuffer.

  • @floupinette Part of the reason is that :substitute has been around since ed, so for backwards compatibility the shorthand :s needs to be :substitute. But as pointed out, :sb is the shorthand for :sbuffer (though I would guess that :sb1b would be interpreted the same as :s/1/; that is, delete the first 1 in the line or error)
