How to switch workspaces with just one action?

[Asquator]

Currently, to switch workspaces I always have to complete the action:
When switching with a shortcut, I have to release the Super key
When switching with touchpad gestures, I have to click to choose the right workspace

I wonder if there is a quicker way to do that, when only one action is needed, whether with keyboard or touchpad.
It would be great to have separate triggers for the two modes, like different shortcuts or 3-4 finger gestures.
Thanks
