in openSUSE KDE, the win key is used as a secondary key---meta key. and open the Program menu shortcut key is set to ALT+F1, this for the habit to open the program menu with win key person, is indeed some inconvenient.
In the foreign forum to see a gadget---ksuperkey, the role of this tool is that when you press the meta-key, it will send alt+f1 to the system, the equivalent of pressing the Open Program menu shortcut keys. Let's see what the original says:
Ksuperkey allows you to open the Application Launcher in KDE Plasma Desktop using the Super key (also known as the "window S key "). If you are down the Super key it would still act as a modifier key, allowing you and use it for other keyboard shortcuts.

At the same time, in the domestic forum to see some other methods, I have not tried, looked at, think there is a problem is this, meta-key is not can not be used as a secondary key? Also recorded:
1. First run the Xev at the terminal, position the cursor to the small window, press the WIN key, the terminal will show its keycode
2.sudo Vim/etc/x11/xmodkey
In the end add a sentence
KeyCode Key:f13
The key is what you see in the first step keycode
3.sudo Xmodmap/etc/x11/xmodmap
4. In the Program menu, right-click, select "Program Startup Settings" in the shortcut keys set it OK
