How can I map Win + L to lock screen in KDE4?

Question

How can I map the keyboard shortcut to locking a session in KDE 4?

Answer 1

Here's what you could do to remap session locking from default Ctrl+Alt+L (tested with KDE4.3) :

1. Go to "System Settings" (KDE menu).
2. Choose "Keyboard & mouse" (on "General" tab).
3. Choose "Global Keyboard Shortcuts" on the left.
4. Choose "Run Command Interface" from "KDE component" dropdown list.
5. Choose "Lock session".
6. Select "Custom".
7. Click on "None" (button changes to "Input...").
8. Compose your desired sequence by pressing appropriate buttons on your keyboard.
9. Click "Apply".

Answer 2

I imagine that man xmodmap will help with the keybinding part of it.

I don't know enough of KDE to help with what keysequence already locks the screen.
