Hi, I'm a dummy in this world, but learning.
Besides previous advise, you can find more features and hot key control in:
Menu -> System -> Configuration -> Configure your Destop (Kconfig ??) -> Accessibility -> Keyboard Shortcuts
It let you to assign hotkeys to Maximize active Window, or Run a program that you've choosen.
Other solution presented before, gives you into mouse movements for going back in Konqueror Window, that it is great for me at this point (I was all my live Windows' user)
