But doesn't the original "single-keypress" theme shares that problem anyway? It trades the ability to "delete some of the it again if he decides to" away, in exchange for something else (probably "quicker input" or "perceived ease of use"). > ....

I think that is independent, is an easy to fix (e.g. 1..9 A B C...Z), and is a chicken-and-egg issue. If the input mechanism had "enough leading letters to disambiguate" semantics from the beginning, I am reasonably sure that list_and_choose() would have implemented its choice as not small integers but distinct letters. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
