I really appreciate the on screen menu, being able to open the keyboard. But I’d really appreciate some kind of shortcut or something in there to be able to use ESC, ALT and/or F-Keys. As of now it’s not possible to open full-strength applications easily without having the OSs onscreen keyboard open instead of android keyboard.
This could be done as a little toolbox, sticking to the keyboard (similar to the Termux or Terminus applications).
Or for the time being until something like that is developed at least a ESC entry in the toolbox.
