Pressing this button will activate 2 modes at the same time:
-
the "left button lock" mode: the direction pad will act as if you
moved a mouse while holding its left button at the same time. It
will allow you, for example, to use sliders or other dragging controls.
-
the navigation buttons, at the top right, will allow you to move
from one link/field to another (normally they scroll the page
up/down).
Press again to disable these 2 modes.

in the interface, it will allow you to open a link, execute a function, etc
(same as if you tapped on the screen).
This button is like a mouse's right button. Depending on where you are in
