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.
