Using: openSUSE 12.2, KDE.
Having used Ubuntu/gnome 2 for several years, I had become used to the speed of ALT+Space to bring up my window menu for rapid maximize/normalize/minimize functions. Eventually I found this bound to ALT+F3, a horribly awkward binding in KDE (as found in the Wikipedia shorcuts table). I couldn’t find any easy documentation on changing this, so I thought I would share here.
Applications -> Configure Desktop -> Shortcuts and Gestures -> Global Keyboard Shortcuts
here, as a newbie, I hadn’t realized you could drop-down on “KDE Components” (with so many options, I start to miss things). I honestly thought Amarok was the only program with global shortcuts! FACE PALM
Anyway, go to KWin and search “menu”. The only option that appears for me is just what you want: “Windows Operation Menu.” I rebound mine to Alt+Space.
Once again, altogether thats:
Applications -> Configure Desktop -> Shortcuts and Gestures -> Global Keyboard Shortcuts | KDE Component: KWin : Search: “menu”

If anyone has improvements on my instructions, please share. Hope this helps save someone time.
