If I set any shortcut in Settings Manager -> Windows Manager -> Keyboard, using Super key anything other works. It just gets ignored nothing happens. Settings Manager -> Keyboard, shortcuts work fine with super key.
For example when I set Maximize window to Super+m, ignores. Ctrl+m/Ctrl+Alt+m ... does work. whisker menu Super shortcut and launch terminal with Super + T both work in Settings Manager -> Keyboard.

If you ever expect any help on this, you should probably mention which window manager you're using instead of referring to some obscure settings GUI ...
