Hello to all.
I have a small collection of Toshiba Portege M400 pen-tablet laptops and am currently working toward getting all tablet-related functions working as expected. The majority of these haven’t been a problem – the tablet itself is a Wacom serial type and worked out of the box, and handling screen rotation was achieved by mapping a button to a script – but there’s one function button I haven’t been able to get working yet: the “multi-function” button, which is a thumstick/joystick on the bottom of the screen bezel.
What I’d like to be able to do is get this emulate a mouse so that moving the stick moves the mouse pointer, and depressing/clicking the button itself acts as a left-click or enter. The problem is that each movement of the stick is regarded by the OS as a two-key combination: either Super_R+[a number key] when checking through xev, or Mod4+[a number key] in the Keyboard Shortcuts control panel. I have no idea how to map those key combos to “mouse pointer up”, “mouse pointer left”, etc. Anyone have any experience in this arena?
