How to switch to fullscreen/window mode while playing?

Zed

Hello,
Is it possible to switch to window mode if I started the game in fullscreen mode?
I could not find such option.

If I start in fullscreen mode then I can't even use Alt+Tab to switch to another window, the program won't let me do that.
Thanks

Zed

I found it:
Options -> Show Taskbar -> click the settings icon -> go to Video settings

You can also just press F11 to switch between windowed and fullscreen modes.

The fast way to open the task bar is to press Shift-Escape.
