Splits

Splits are very useful i.e. in vimdiff. So here some keybindings.

Help: :help splits & :help CRTL-W

More natural splits opening

Open new split panes to right and bottom, which feels more natural than Vim’s default:

set splitbelow
set splitright

Resizing splits

Vim’s defaults are useful for changing split shapes:

"Max out the height of the current split
ctrl + w _

"Max out the width of the current split
ctrl + w |

"Normalize all split sizes, which is very handy when resizing terminal
ctrl + w =

More split manipulation

"Swap top/bottom or left/right split
Ctrl+W R

"Break out current window into a new tabview
Ctrl+W T

"Close every window in the current tabview but the current one
Ctrl+W o
