What are the three buttons above touchpad in the Dell Latitude E6520 laptop?
I wonder what are the three buttons added to the touchpad/keyboard of the laptop Dell Latitude E6520 as the below snapshot.
I do a google search as here though nothing helpful for me.
If you know that they are, please share.
The buttons on the left and right are left and right clicks for when you're using the "pointing stick" between G, H, and B.
The middle button will either be a middle click, some sort of scroll, or a "lock" for the left click to make clicking and dragging easier.
They are the buttons that go with the trackstick.
