I meant for example, if I hit Meta+o then I could press any single key after that.. i.e. 't' for terminal, 'f' for file manager, 'b' for browser. KDE doesn't support that, as far as I know.. nothing built in, anyways.

True nothing fully built in. With jumpapp installed though and adding Custom Shortcuts, I have the following:

    Alt  B --> Browser (eg Firefox)

    Alt  K --> Konsole

    Alt  T --> Thunderbird

    Alt Z --> zim

    Alt D --> doom

jumpapp will open the app if it is not open and switch to it if it is open. It's way to handy to forgo IMHO. But jumpapp is a dependency, true.
