"Jim Gettys gave a keynote speech at Linux Expo, wherein he spoke of the need to support disabled users. He's quite right. We need to support them -- not out of any bleeding-heart concern for them. We need to support them because the interfaces that enable them to use computers *at all* enable us to make better use of them. A good interface is a good interface whether you can't see or can't hear or can't type or can do all of these. In particular, people who can't see have trouble with a GUI, and people who can't type have trouble with a command-line."

"You may have noticed some tension between users of the command line and the GUI. There is a very simple explanation. The command line is based on recollection, and the GUI is based on recognition. This paper explains why each has its place, and explores ways in which they can be combined. We start by explaining how a "pure" version of each works, how they are combined in real life, and how we can use this perspective to find new avenues for exploration."
