+@cindex pinch to scale
+@findex text-scale-pinch
+ The command @code{text-scale-pinch} increases or decreases the text
+scale based on the distance between fingers on a touchpad when a pinch
+gesture is performed by placing two fingers on a touchpad and moving
+them towards or apart from each other. This is only available on some
+systems with supported hardware.

+@findex mouse-wheel-text-scale
+ The command @code{mouse-wheel-text-scale} also changes the text
+scale. Normally, it is run when you press @key{Ctrl} while moving the
+mouse wheel. The text scale is increased when the wheel is moved
+downwards, and it is decreased when the wheel is moved upwards.
