Most keyboard shortcuts not working

Hi, most keyboard shortcuts in UE editor don´t do anything for me. The system ones like CTRL-Z, CTRL C/V/X work but things like switching camera bookmarks, show/hide viewport toolbar (ctrl shift t), toggle Realtime (ctrl-r) don´t work. I do see them listed in the menus next to the commands and did not change anything related to them in Prefs. What gives?

UE4 4.23.3 on Windows 10.
