Presume `other-window' navigates clockwise, and current focus is on window 1.

,-----.-----.
| [1] |  2  |
|--- -+-----|

'-----.-----'

3/4 windows in Emacs are common in HiDPI users.

You have to press {C-x o} twice to go to window 3. Meanwhile, you have to
release the Control key to avoid the invocation of `delete-blank-lines' which is
bound to {C-x C-o} by default. It's painful for your little finger without an
external keyboard.

What will happen if we make {C-x o} bind to a transient map? {C-x o}, forget the
Control key and press "o" twice. It's easier to navigate to window 3 when
compared with the previous one. An analogue is `windmove-left' which is bound to
{S-<left>} by default. In practice, we press {S-<left>} without releasing of
Shift key since it's convenient for the next movement. The same for {C-x o} but
"the Shift key" is pressed implicitly when we enter transient state

Bonus: we can bind "O" to a counterclockwise `other-window' function.
