Is your feature request related to a problem?
When typing “/checkbox” via an external keyboard, it is not possible to select the “checkbox” block from the menu shown with the keyboard. It’s only possible via touching the screen.
Just pressing enter doesn’t work because of the system’s “word suggestions” and arrow down to select the shown menu entry also doesn’t work.
Describe the solution you’d like
Allow using the arrow down to select the menu entries. Or even better, when the menu is opened anyway, preselect the first entry to make it usable via “enter”.
