The wikipedia article about ASCII provides some roundabout info as to why things are the way they are re: the "tty driver". "Advanced Programming in the UNIX Environment" by W. Richard Stevens remains an excellent place to acquire in-depth understanding of terminal I/O. "Xah Lee", one rather famous internet troll, wrote some stuff about emacs in general & its keyboard mappings. Not emacs savvy enough myself to decide, but if you haven't read his rant about emacs you could check his web site. > > I use "<" and ">" to move between tabs in the Elinks browser.. both > > mnemonic and useable.

Hmm.. not sure it's idiotic.. perhaps not from the saleman's viewpoint :-) Fact of life.. Letters with underlines on menu items or toolbars look less cool than letters without underlines. Perhaps I shouldn't be this critical.. to be honest, M$ do such a much better job of making GUIs keyboard-navigable than their *nix counterparts that it's embarrassing. When I wrote "discoverability" I was really referring to a marketing concept that postulates that most everything in a "modern" interface should be made such a "cool" trip for the user that he becomes capable of finding out for himself how he's supposed to achieve whatever they, the designers of the "modern interface" have imagined that he or she, our naive user should be doing. Since our naive user intially has no clue what he should be doing in the first place, discovering how he or she could do it, and therefore where the designer is concerned, designing a GUI that makes such tasks discoverable for said naive user.. should be fun... As I understand it, not only is the "modern gui" designed to do the original job well, irrelevant of what the prospective job might be, but it does feature one additional priceless piece of true wizardry, namely that it effectively teaches the user how to actually do it.. without explicitly resorting to teaching the naive user.. since "teaching" would actually not be cool.. etc. I looked for real-life examples.. and I.. discovered.. that notepad and pico/nano are pretty much the only editors that come close to the ideal of "discoverability".. Unfortunately.. respectable tools such as vim and emacs fall short of our expectations. :-( Mind you, discoverablity is not just marketspeak.. with an interface that's discoverable, "users" can save themselves the indignity of reading manuals, and conversely feel "empowered" by the experience.. Satisfaction across the board.. since decent doc is expensive.. also saves "software" manufacturers millions. I don't know how relevant this is to the software interface, but a barebones example of "discoverability" that clashes with the final "useability" of the product is those pesky arrow keys that were added at some point to the traditional typewriter keyboard.. easy to discover.. highly mnemonic in case you are forgetful.. but unless I'm blind drunk or in such an alien context that I cannot function anyway, I don't like them very much. If keyboarding skills mean anything, check out Benedetti Michelangeli's rendition of Debussy's "La Cathedrale Engloutie".. was on youtube last time I looked.. I doubt he learned his stuff on an enhanced piano keyboard with discoverable keys.. but what do I know.. Never fancied myself as a champion typist, reason I thought I should become more intimate with the keyboard was that I found it odd that I could write with a pen effortlessly, an obsolete skill if there ever was one.. and suffered from a crippling case of keyboarding incompetence. :-) Thanks, CJ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
