I've read up on imwheel and editing the XFree configuration file, but still have not found what I'm looking for (or maybe I read too fast). Most people have successfully mapped side mouse buttons for "back" and "forward" in their web browser. Has anyone set up a 4 button mouse and mapped the thumb button for double-click? Thanks.

I actually managed to get imwheel to support a double-click mapping to one of my extra buttons. To do this, though, you need to be sure your X server supports the keypad mouse. To find out if it does, press Control-Shift-NumLock. Then press one of the keypad numbers to see if the mouse moves on the screen. If it does, you can create a mapping in imwheelrc to support the double-click button on the keypad (+). Turn off the keypad mouse first, though, by pressing Control-Shift-NumLock again.

In your imwheelrc file, you will want to add the following line (suitably modified for your preferred button, of course):

Then, restart imwheel and test to see if it works for you. To get imwheel to work properly, I have to start it with

Hope this helps,

Thanks wont! Worked like a charm!

could you elaborate on the code
None, Right, Control_L|Shift_L|Pointer_EnableKeys|-Pointer_EnableKeys|-Shift_L|-Control_L|KP_Add|-KP_Add|Control_L|Shift_L|Pointer_EnableKeys

when i put that in and run imwheel i get:
imwheel started (pid=25561)
Unrecognized wheel action in config.
Right
User defined signal 1
