I have a Logitech K800 running Windows 8.
I have this extremely annoying issue where my keyboards keys appear to remap while I'm working. It's difficult to pinpoint exactly the cause or when it happens, but my " and @ keys first appear to swop, and after a while I am unable to type a # as it maps to something else then.
Programs I can identify I use is Netbeans as this is where I pick it up first, but that is purely just because I use Netbeans most of the day. I also have another program called keyboard-mouse-share which shares my keyboard and mouse (much like Synergy) but I have turned it off with the same result.
I know it will be difficult to pinpoint exactly what could be causing this, but is there a log or something where I can go to see what the issue may be?
Doing some further research it appears to be a regional language issue. If you experience the same change your keyboard layout from US to UK or vise versa (depending on the keys swopping)
I got a keyboard (Logitech Wave, pictured below) which I'm very happy with. Unfortunately, the manufacturer has changed the button for right-click for a FN key.
Is there any program to remap the FN key to something else?
I once asked a similar question on StackOverflow, but regarding the Fn key on a laptop. On a laptop, the Fn key is not being interpreted by the OS, so it's impossible to remap in most cases. Have a look at the suggested answer, maybe in your case it will work.
