Is there any way to set keyboard shortcuts for a single keystroke? I'd like to bind the Meta key to open Application Launcher. This behavior is similar to Unity and Gnome 3. When I press input to set the keyboard shortcut, it is always demanding at least two keys. Can this be manually defined or does this require a feature request?

You can assign global action to one key, but there is some kind of blacklist - you can't use characters and numbers and you can't use modifier keys. You may use F1-F12 and some others, though.

Meta is considered modifier key. You may assign it to launcher using workaround, but you will loose it's modifier key capability (and plenty of keyboard shortcuts) in process.

There is also another brainstorm idea specifically for that. Please read that discussion - it seems that Qt is not capable of that by design, but Ubuntu guys somehow did it.

Okay, thanks for the details

I just place a vote on the thread you linked to. The thing is, I have 4 different laptops and I go between using KDE (primarily), Unity, Gnome 3 and Cinnamon. It's nice to have consitent keyboard shortcuts from one desktop to another. For example, it is annoying that Find is Ctrl H in Gnome apps. It makes so much more sense intuitively to use Ctrl F for find and Ctrl R for Find/Replace, like the way KDE has it. But then, KDE doesn't have a shortcut by default for Save As. It's easy to configure, but that should really be set to Cntrl Shift S by default, like just about every other desktop environment (Windows and OS X included).
