With the keyboard shortcut assigning screen in kde 3.x it used to be
possible to expressly use just the keyboard to set and clear shortcuts.
I could "tab" & down-arrow my way to the function for which I wanted to
modify the shortcut. Then I didn't need to click on it before I could
use <alt>+N to clear the shortcut(s), <alt>+U to initialize an input
pop-up for a custom shortcut, or <alt>+D to set a default... The only
time I needed to "click" on anything was if I wanted to assign an
alternate (second) shortcut...

With Kde 4.1.3 I need to actually click on the function to expand it to a
detailed view where similar shortcuts can be used to set or clear the
shortcut assignment.  Since I can highlight the function involved with the
arrow keys It shouldn't be that difficult to cause the enter key to
expand the currently highlighted function.
