Cheat sheet

Move and renumber windows

Goal

The window list reads 0:editor 1:logs 2:tests 3:shell.

An index is a slot in the window list. These three commands change slots without closing anything:

C-b .
prompt for a new index for the current window
swap-window at C-b :
trade the current window with the one holding the marked pane
movew -r at C-b :
renumber every window from 0, closing the gaps

The mark is the same one from C-b m: mark a pane in the window you want to move, go to the window you want it to trade with, then run swap-window.

Do this

Press C-b 3 to reach tests, then C-b ., type 2, Enter.

The list shows 2:tests.

Press C-b 1 to reach editor, then C-b m.

Its pane is marked.

Press C-b 0 to reach logs, then C-b :, type swap-window, Enter.

editor is now at 0 and logs at 1.

Press C-b :, type movew -r, Enter.

7:shell becomes 3:shell, leaving 0:editor 1:logs 2:tests 3:shell.

Replacing an occupied index

move-window refuses an index that is already taken, unless you add -k to replace whatever is there.
