One of my clients has a bit of difficulty typing because of his motor neurone disease (MND) – he is a pretty good typist, but now occassionally presses the ‘wrong’ key – this is generally one of the neighbouring keys to the one he wants. For example he might type hjello for hello.
However, this seems a bit ‘over the top’ for this client who only has occasional problems. So, we made a simple ‘virtual’ keyguard. This filters out key quick presses from neighbouring keys.
You can download and try the script from here. To run the script, you need to download AutoHotKey . Both of these programs are free and open and provided with no liability. Hopefully they will be useful to someone else.
 AutoHotKey is a great little program that we fairly regularly use to make bits of the computer more accessible – for example getting keys on a keyboard to do things that people find difficult to do otherwise.
