No, sorry, HotkeyNet uses pixels.

But can't you use percent anyway? You don't need to handle resolutions separately. You can do all your calculations in percent. Then, when you write a number in the script, multiply it by the screen size.

Instead of this:

Code:
write_to_script ( y );
You will have this:

Code:
write_to_script ( y * screen_size );
It's only one extra multiplication.
