wrong key mapping Volla Tablet + Volla Keyboard German version
-
I bought the official keyboard to the Volla Tablet. I have the German Keyboard Layout.
My system settings are on German language / german keyboard.
Nearly all keys are mapped correctly (The German z / y are correct, most German mappings of special keys above the numbers are correct.)Yet there is one annoying fact:
On the keyboard markings it says that<,>and|are on the 3rd level (Alt-GR or right Alt key) ofy,xresp.c.
But when I useright Alt + y,right Alt + xresp.right Alt + cthe mapped keys are»,«resp.¢.
Other third level keys asµ,@or€are working fine. There are more third level keys but I don't know their correct mapping.This is a Volla Keyboard specific problem. My external bluetooth keyboard maps all keys correctly.
My guess is that this happens because there is the physical key missing on the smaller volla keyboard which is normally present in large keyboards for these three keys and the mapping automatically uses the next numbered key.
- Is there a temporary fix e.g. by remapping these keys?
- Shall I file a bug report somewhere or is this forum enought?
Thanks so far.
Some information, fwiw:
