Roberts and Thomas P. Moran in the April 1983 Communications of the ACM. This study compared 9 different editors (including Emacs, Teco, and several Xerox mouse-based editors) using predicted and actual times to perform a variety of tasks. There were a couple of interesting things in the paper. First, in their predicted times, they concluded that "the homing time between the keyboard and pointing device is not a major problem". The exception to this was the WANG editor that relies heavily on function keys separate from the main typing array. Second, in the actual timings with expert users the 2 fastest editors were mouse-based, the third was the WANG. -- Larry Rosenstein Object Specialist Apple Computer AppleLink: Rosenstein1 UUCP: {sun, voder, nsc, mtxinu, dual}!apple!lsr CSNET: lsr@Apple.CSNET
