Tim, All,
For a long time I used compiz with kde3 due to the efficient and elegant way it allowed you to manage and manipulate your multiple desktops.
A majority of users have the default setting of 4 desktops, but never use desktops 2-3-4 because there is no intuitive way to manipulate all desktops from the keyboard. They just keep cramming all the windows they have open on desktop 1.
What compiz did was make use of the 'Win' key that is on 99% of the keyboards now to allow easy desktop switching from the keyboard. This really makes using desktops 2-4 efficient because you never have to reposition your hands from the keyboard to grab the mouse and click on the pager or rt-click and choose another desktop.
I know this is the nitty-gritty 'little-stuff', but that has always the foundation of kde3 and it should continue in Trinity. I propose the following as default keyboard shortcuts incorporating the 'Win' key. Try them out and you will be amazed how much simpler switching desktops and moving windows between desktops becomes using the keyboard. (the Win key is also in the correct location to prevent losing your finger position over the 'F' and 'J' keys and completely having to reposition your hands after affecting a switch or move from the keyboard.
Try these out in kdeglobals:
Walk Through Desktops=Win+Tab
Switch to Next Desktop=Win+Right Switch to Previous Desktop=Win+Left
Window to Next Desktop=Win+Alt+Right Window to Previous Desktop=Win+Alt+Left
