According to the Acer User Guide
(https://www.synapsenow.com/synapse/d...s/tmc100ug.pdf) on
Page 14, the descriptions are:
#4 - Touchpad.
#5 - Click buttons (left, center and right) - The left and right buttons
function like the left and right mouse buttons; the center button is a
4-direction scroll button.

While you're checking on the online guide, do a Search for "Fn" without the
quotation marks. You will have 28 results within the guide which may assist
you. If that doesn't help, contact Acer's online support. They're pretty
good.
