In the old Elements window of Math it was possible to select formulas with the keyboard according to: https://help.libreoffice.org/Math/Formula_Shortcut_Keys#Navigation_in_the_Elements_Window Now the Elements window is gone and its functionality is available in a side pane, but I can't navigate to the formulas with the tab (or any other) key and insert a formula to the Commands window. All I can do is to select the category listbox and choose another category from that. I think it would be nice to have back this accessibility feature.
