I had been using imwheel to work this but imwheel is old and I found a better way.

1- Install xautomation and xbindkeys

2- Create this text file and name it .xbindkeysrc, put it in your home directory


# For the benefit of emacs users: -*- shell-script -*-
###########################
# xbindkeys configuration #
###########################
#
# Version: 1.8.0
#
# If you edit this file, do not forget to uncomment any lines
# that you change.
# The pound(#) symbol may be used anywhere for comments.
#
# To specify a key, you can use 'xbindkeys --key' or
# 'xbindkeys --multikey' and put one of the two lines in this file.
#
# The format of a command line is:
# "command to start"
# associated key
#
#
# A list of keys is in /usr/include/X11/keysym.h and in
# /usr/include/X11/keysymdef.h
# The XK_ is not needed.
#
# List of modifier:
# Release, Control, Shift, Mod1 (Alt), Mod2 (NumLock),
# Mod3 (CapsLock), Mod4, Mod5 (Scroll).
#

# The release modifier is not a standard X modifier, but you can
# use it if you want to catch release events instead of press events

# By defaults, xbindkeys does not pay attention with the modifiers
# NumLock, CapsLock and ScrollLock.
# Uncomment the lines above if you want to pay attention to them.

#keystate_numlock = enable
#keystate_capslock = enable
#keystate_scrolllock= enable

# Examples of commands:

"xbindkeys_show"
control+shift + q

# set directly keycode (here control + f with my keyboard)
"xterm"
c:41 + m:0x4

# specify a mouse button
"xterm"
control + b:2

#"xterm -geom 50x20+20+20"
# Shift+Mod2+alt + s
#
## set directly keycode (here control+alt+mod2 + f with my keyboard)
#"xterm"
# alt + c:0x29 + m:4 + mod2
#
## Control+Shift+a release event starts rxvt
#"rxvt"
# release+control+shift + a
#
## Control + mouse button 2 release event starts rxvt
#"rxvt"
# Control + b:2 + Release

# dolphin go back
"xte 'keydown Alt_L' 'key Right' 'keyup Alt_L'"
b:9

# dolphin go forward
"xte 'keydown Alt_L' 'key Left' 'keyup Alt_L'"
b:8

3- Create an autostart entry text file in /home/your_user_name/.kde4/Autostart
Name it xbindkeys.desktop, here is what to insert

Voila, works perfectly in firefox, konqueror and dolphin. This is using an ms explorer mouse but I believe it should be okay with other side button mice. Good Luck

Thanks for the tutorial! But, why are these buttons not standard in KDE?

Additional mouse buttons cannot be used due to a limitation in Qt.

Thank you for the in depth info!

Is it planned in future?

Unfortunately I don't know at this point in time. It could be though...

Someone is working on implementing the necessary underlying Qt bits, but I don't know the current status.

I don't know what limitation in Qt you are talking about. Have a look at http://doc.qt.nokia.com/4.7/qt.html#MouseButton-enum. I have successfully used Qt::XButton1 and Qt::XButton2 in ktikz. Also in Arora these buttons are used and work.

so it should be now possible to implement those clicks in dolphin and other Qt/KDE apps without any workarounds or what?

My mouse side button works in firefox but I can't bind it to back in Konqueror...

is this still the case?

Have you tried the XBindKeys method documented above?
