The last time I've really tried out KDE (many years ago, in the KDE4 era) it didn't work and I had to install an extension (that didn't quite work for me) to get that to work. But I've heard that they've changed it later. After some configuration I've installed XFCE on this PC and was much happier. I even found a menu and a configuration for XFCE that worked like I wanted it to work.

I specifically remember that the input handling code in KDE was adjusted a few years ago to handle single-key shortcuts where the single key is a modifier, esp. the Windows key.
