> but try to consider these groups: older people who will not learn precise right hand movement anymore, people with temporary or permanent right hand injury, people with no right hand, people with missing right hand fingers, etc. Perhaps, but that does not seem to be a software issue, at least, not a software issue with the X window system itself. If you want to consider such things, it is probably more important if someone who is concerned about such things wants to design hardware specifically for such people. Allowing you as long as you want to type something instead of adding a time limit can be helpful for such people (since having less fingers or only one hand might make it take longer to type) but it can also be helpful for any other people for whatever reason (e.g. you have to answer the telephone before continuing to type on the computer, etc). Accessibility features are for everyone.
