Changing the size of the split screen in vimdiff
vim
Solution
You can use any windowing command in `vimdiff`, for example CTRL-w < to make the left window one column smaller. This can also be combined with a count, for example CTRL-W 5> to make the right window 5 columns smaller. Consult the help page with `:help CTRL-w` to get a list of window commands.
Additionally, you can use the mouse to change the size of the windows by clicking the boundary between both windows and dragging it into a direction. You might have to enable mouse support by issuing `:set mouse=a` first.
Problem
I only know two commands for dealing with vimdiff: `Ctrl-w Ctrl-w` switches windows and `Ctrl-w =` makes the two windows equal width if they became uneven due to, for example, resizing the terminal. How can I make the left screen much larger than the right, for instance?
