Can I emulate a mouse with my pen?

[AtleastItried]

I have a fairly simple goal: Make my Surface pen act like a mouse when I'm pressing it onto my screen.

Right now, some things are impossible to do in windows with only a pen and a touchscreen, especially when it comes to the web. An example would be google calendar, where ever since the pen behaviour was changed, you can't reorder old things. With a mouse, you can just drag them, but without one you have no way of doing that.

What I have thought would be useful is a script that would essentially see where I put the pen down, prevents that, and when I drag it it emulates mouse input. But here I have run into problems:

[*]How do I trigger something when my pen is touching the screen? There is a way for left clicking (#LButton::), but I can't find anything about the pen.
[*]How can I update my mouse location while draggin the pen?

I would be very happy if someone could help me with those two points.
