View Full Version : [all variants] Emulating Middle Mouse Button Behavior

Hey all I'm new here (and new to Ubuntu, relatively new to linux as well). I've got 8.10 installed on my laptop, and my touchpad doesn't have a middle mouse button. One of the apps I use frequently requires middle mouse button dragging (not just clicking), so I was wondering if anyone had any suggestions on how to emulate this using a control key (eg. Windows Key + LMB = MMB).
Thanks all.
edit: I realize that RMB->LMB = MMB, however my touchpad is somewhat worn to say the least, and doing this usually results in awful things. It would be nice to have a more reliable solution.

I have done the same on my laptop, here's the full description of how i did it:
http://linuxaleph.blogspot.com/2008/11/mapping-middle-click-to-keyboard-key.html
basically, sudo apt-get install xkbset, edit the file /usr/share/X11/xkb/compat/mousekeys and remove everything between interpret.repeat= False; and // New Keysym Actions, then use Preferences - Sessions to autostart a script like this as you login:
#!/bin/bash
# set XKB layout
setxkbmap -layout us
# turn on mousekeys
xkbset m
# stop mousekeys expiring after a timeout
xkbset exp =m
# map keysym to other keysym
xmodmap -e "keysym Menu = Pointer_Button2"
# this also works
# xmodmap -e "keycode 135 = Pointer_Button2"
use xev to find the keycode if you don't want to use the Menu button

Hi super jamie. That tip actually (finally) enables me to reassign my search key as a middle mouse button. However, since it relies on mousekeys, it also disables my numeric keypad. Do you have any solution for that?

Other people reported the same behavior in this huge thread on the MX Revolution:

Someone posted an alternative solution that doesn't use mousekeys:

It's several years old, though, so I don't know if it still works.
There are also other suggestions in that thread, such as mapping the middle mouse function to the left thumb wheel...
