Vim: Move window left/right?

Ctrl w gives you the "windows command mode", allowing the following modifiers:

• Ctrl w + R - To rotate windows up/left.

• Ctrl w + r - To rotate windows down/right.

You can also use the "windows command mode" with navigation keys to change a window's position:

• Ctrl w + L - Move the current window to the "far right"

• Ctrl w + H - Move the current window to the "far left"

• Ctrl w + J - Move the current window to the "very bottom"

• Ctrl w + K - Move the current window to the "very top"

Check out :help window-moving for more information

This one is the most useful for me (and is probably the right answer to the question):

• Ctrl W + x OR Ctrl W + Ctrl x - Rotates the current focused window with the closest window to the right.
