If you are using Prelude you can just use C-c s (prelude-swap-windows). From the Prelude documentation:

C-c s runs the command crux-swap-windows (found in prelude-mode-map),
which is an alias for crux-transpose-windows in crux.el.

I've got it. There is a utility called xbkeys for setting accessibiltiy options for xorg.

From xbkey manual:

To switch sticky keys on or off, and optionally set or reset:
() two keys pressed at the same time stops sticky keys;
() a modifier pressed twice will be locked:

    [-]{sticky|st} [[-]twokey|[-]latchlock]...

I ran this:

$ xkbset sticky -twokey -latchlock

That command can go in .xinitrc

# turn on stickykeys. don't let two keys pressed at the same time disable it.
# don't turn on "latch lock", ie pressing a modifier key twice "locks" it on.
xkbset accessx sticky -twokey -latchlock

# don't expire these settings. (run xkbset q exp for details.)
xkbset exp 1 =accessx =sticky =twokey =latchlock
