This add support for the fast switching between programs on the budgie desktop, like the behaviour on Windows or Ubunutu.
The <number> is a reference to the nth pinned program in the taskbar.
Superkey+<number>
- Switch to the pinned program, if already open, else start a new instance for the first time
- If an instance of the program has already the focus, switch to the next instance
Superkey+Alt+<number>
- Like Superkey+
<number>, but reverse switching between instances
Superkey+Shift+<number>
- Force creation of a new instance of the pinned program
