[Optimoz] What ways are there to make gestures?

[Gonzalo HIGUERA DÍAZ]

Hello.

I am asking a general question based on a couple of gestures that
baffle me: "Open Links in Windows" and "Open Links in Tabs". In both
of them, the gesture is described as starting with an asterisk, and I
have no idea on how to execute them. So the specific question is: how
do I trigger these gestures? The more general question would be: is
there some documentation as to what gesture codes are possible?

Thank you.
