Can you increase the span of a window?

Question

Let's say I have a window layout like below:

[1][2]
[3..3]

And I want to expand window 2 to look like this:

[1][2]
[3][2]

So window 2 will now be full height

Answer 1

You can do this by moving window 2 rightwards (<C-W><S-L> or :wincmd L):

• Initially, with focus on window 2:

  

• :wincmd L:

  

To get back to the original arrangement from here, move window 3 downwards: focus on window 3, then <C-W><S-J> or :wincmd J.
