I mainly use windows and use Linux/Kubuntu occasionally, and would love it if the same Windows shortcuts can be applied in KDE 4.

Shortcuts that I would love to have.

1. Winkey - Launches the start menu.
2. Ctrl+Shift+Esc - Brings up taskmanager
3. Winkey+d - Issues the minimize all comand
4. Winkey+e - Open up Naultius

Can anyone suggest and method to bind the keys into doing the correct stuff?

Edit #1: 

5.Also Winkey+L - To lock the computer
