+.Sh POINTER MOVEMENT
+The pointer can be moved with the use of the keyboard through bindings.
+C-[UP|DOWN|LEFT|RIGHT] moves the pointer a small amount, while
+C-shift-[UP|DOWN|LEFT|RIGHT] moves the current window a larger amount.
+For example, to move the pointer to the left by a small amount,
+press C-LEFT.
+To move the pointer down by a larger amount, press C-shift-DOWN.
