I would like to associate the Start menu with the Windows key on the keyboard?
In KDE 4, the sequence to find the shortcut key is
System Settings -> Keyboard and Mouse -> Global Keyboard Shortcuts -> Plasma Workspace
then modify the shortcut key for "Activate Application Launcher Widget". An alternative way to get to the shortcut is to simply right-click on the Kickoff menu and choose "Application Launcher Settings".
Additionally, unless you configure the Win key, it acts as a Meta modifier by default, and cannot be used as a shortcut. To change this, create a file ~/.xmodmap and put the following in the file:
keycode 115 = F14
This makes your system think the Win key is actually the F14 key. Note: different keyboards sometimes have different key maps for the Win key (i.e. on my Thinkpad, the keycode for the Win key is 133). You can use the application "xev" from the terminal to determine which keycode applies to your keyboard.
You can modify the file
and add the command
if [ -f $HOME/.xmodmap ]; then
to the bottom of the file, which should load your
.Xmodmap on startup.
.Xmodmapcreation and the Xsession modification and then logout/login (or run
/usr/bin/xmodmap $HOME/.xmodmap) before attempting to modify the shortcut key.
