> Usable means an interface which is (i) consistent and (ii) well suited to the task at hand. No it doesn't. Usable as in Usability is defined in the ISO-norm 9241-110 by seven principles, a summary can be found here: http://www.userfocus.co.uk/resources/iso9241/part110.html http://www.userfocus.co.uk/resources/iso9241/part110.html "suitability for the task (the dialogue should be suitable for the user’s task and skill level); self-descriptiveness (the dialogue should make it clear what the user should do next); controllability (the user should be able to control the pace and sequence of the interaction); conformity with user expectations (it should be consistent); error tolerance (the dialogue should be forgiving); suitability for individualisation (the dialogue should be able to be customised to suit the user); and suitability for learning (the dialogue should support learning)." vim falls short in discoverabilty and, arguably, in user expectation, and suitability for learning. Though I don't want to further spawn a vim-discussion. Just to show you that you don't seem to know the necessary vocabulary to tell you parent that he is wrong. > You're doing it wrong. Read the bloody manual. Yeah. Way to prove his point.
