Assigning a python command to a mouse hotkey I am using an add-on called hexblender, which has some buttons that are useful for making meshes for finite-element models. I would like to assign one of the button's python commands to mouse button 4. 

When I hover over the button, it says: 


  Python: bpy.ops.hexblender.adjust_nodes_linear()


When I run the command from the command line, it does the right thing. Is there a way to assign this command to mouse button 4? I can assign other things to mouse button 4 but I cannot figure this out.

Any help would be greatly appreciated
open User Preferences -> Input
open some category and click Add New button
insert hexblender.adjust_nodes_linear into the input field
assign some keyboard shortcut
test the keyboard shortcut and if it works, use the X-Mouse Button Control application to set your mouse button action to trigger your keyboard shortcut
