Middle mouse button shortcut

[Jopp]

Mac os, Paintstorm 2.30
the middle mouse seems not available... (And by the way assigning shortcuts in the shortcuts panel isn't really easy, I don't double click in many different ways...)

Right now my 1 St express key (on my xp- pen tablet ) is mapped to command or cmd

A) Cmd is used foremost for my color picker,
B) clicking the right mouse button on my pen together with cmd puts me in zoom mode
C) Now, I wanted to assign a 3rd function by pressing the middle mouse button on my pen together with cmd, to quick-scale brushes

Correctly I'm forced to use another express key to scale my brush but I don't like it because things *can* work also differently. Please add middle mouse button in our available shortcuts... Thanks

yes, the middle button is not available for binding. You can only use third-party content to bind a middle button as some keyboard key.
