Better than teleport: you can fly in the game! Just press # and move - with the mouse wheel you can adjust the speed - and press # again to land.

This doesn't work for me. I can open console and use noclip command though

Yeah, if you press Shift+3 for the # it won't work, Beaker probably uses german keyboard layout.
On english (en_us) layout it's the backslash

Yes on a French keyboard it's *

Sorry for that regional answer. Backslash sounds good. Our # is directely left of the enter key in the lower of those two rows. Whatever floats your boat might be the wrong expression here - please use whatever floats your avatar. There might even be a hint in the settings (keyboard control) but I´m not sure about that.

Haven't seen it in any settings , compared keyboard pictures to find out

Games and Keyboard layouts are funny... sometimes they respect the character changes due to the keyboard layout, sometimes they don't and sometimes they only do it for some of the keybindings...
