oooh, yes. That is cool! Does it has a keyboard-shortcut?

Nope.

Hit ? to see a list of all available keyboard shortcuts.

Too bad.
Where is this "?" located? you mean the "?" key, or?
If it's "?" from the keyboard, then it's writing in the Search box.

It's the ? key on the keyboard. In only works when the focus isn't in any
text-box (If you're using a Mac, that might not be an option for you).

hhhmmm, not too many keyboard shortcuts ...
I used the full-screen option all day, but I think it's more time consuming... was better before when you hide it. In any case 99% of the time you look at the workboard.

In any case, thanks for the answer!

We plan to let you bookmark / shortcut the fullscreen version of the workboard.
