I have an obscure problem with a Logitech K810 Bluetooth Keyboard. Everything works perfectly with the exception of the left shift key, it acts as though I have it pressed down for about two seconds longer than I really do. Right shift key works properly, but the left one runs a little slow. I checked the keyboard out and it doesn't appear to be getting physically stuck. I know it's a small problem but it can be annoying when you type at 120wpm! Perhaps it is simply a glitch that can be solved by mapping the key to appear as the right shift key? I have no idea which is why I'm posing the question to you guys. Anyone else has a similar issue?
