Moving items with hotkeys not working

[Anthony]

Many thanks for the feedback.
I re-installed UR again. Now I can be more specific. The hotkeys work, but not - as I noticed now, in my case - once inside the Template root, using left or right keys. For instance if I put a text item file within the Template/Text icon in the outline pane, I am not able to take the text item out with the hotkeys. Instead up and down keys work also there.
