That's a great idea, especially with my programmable keyboard, thank you. I'll have to see if KDE supports this, but I think it's likely.
EDIT: Turns out it's trivial, I love Linux:

KDE's window manager, Kwin, supports this functionality built it.
Just right click on any title bar on a window, go to "Special Application Settings" -> "Arrangement and access" -> "Shortcut". You can manually type "F8" in the shortcut and it'll work just fine.
You can also go to "System Settings" -> "Window Rules" to manage all rules you've defined.
