Hi Hannes, The desktop manager uses "key combinations" always starting with CTRL+D (like "Desktop") so one can easily remember the possibilities:
CTRL + D followed by CTRL + D — “Desktop Display” to display and switch between all desktops CTRL + D followed by CTRL + A — “Desktop Add” to add a new desktop CTRL + D followed by CTRL + N — “Desktop Next” to go to next desktop CTRL + D followed by CTRL + P — “Desktop Previous” to go to previous desktop CTRL + D followed by CTRL + B — “Desktop Background” to choose a background CTRL + D followed by CTRL + F — “Desktop Fullscreen” to switch fullscreen option as can be seen in https://www.youtube.com/watch?v=zpLY7uQnPsg but unfortunately CTRL+D ("single key") is also used for the "do it" in a playground. As the shortcut handler of the desktop manager is only triggered when the full key sequence is pressed the code can only check if the active hand is in an editor and allow the do it then. At least that is the only solution I've found to this problem so far. This leads to the unfortunate effect you have to press CTRL+D twice in the playground once the desktop manager is loaded. But nonetheless the "do it" is still possible - you only have to hit CTRL+D twice in the playground. Hope this helps! Bye T.
