Remember my complaint about out of the box mapping of just 12 desktops in different desktop environments like XFce?
Because of my different workflows I have 16 desktops predefined, just so I know, with the keyboard shortcut, where to jump to fast and continue where I left off. I only use the mouse when I absolutely have to, or when it's really elegant to do so, so I'm a keyboard shortcut mapping daemon.
I haven't taken the time yet to check into the configuration files, of my preferred Desktop Environments and Window Managers, how to map more keyboard shortcuts to More virtual desktops.
However I'm certain that what you want is scriptable, in at least three Desktop Environments and at least two Window Managers it's just not out of the box
I love digging into configuration files and I've seen this options in a few of them
