Photoshop complete fullscreen mode?

Haebel  wrote Hello everyone, I have the question if it is possible in photoshop to switch into a complete fullscreen mode where the windows bar is gone but you can still edit your picture (I have Elements 12). There seems to be no real answer to this wherever I searched. Hope someone can help!

Do you mean the Windows task bar?

If so, with the Windows task bar set to 'auto-hide' the taskbar and the Editor preference >> general set to 'allow floating documents in expert mode', can you enlarge your document window to fill the screen?
