ok I tried my wife`s BT keyboard. Yes CAPS and ctrl ( I think worked ) let and right and firing too.
Then it went all weird and was controlling the cycling of the keyboard, on-screen controls and the keys.
Nice work sleek :) Don`t know how I missed this. .I have no way of compiling it, is there a binary apk I could try on my GPDXD+ ?
Looking at your git.. I can`t see the .apk :/
EDIT: Found it :) thank you
