Re: [jed-users] Possible FAQ - turn tab indenting off

[Manfred Hanke <Manfred.Hanke@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Wondering whether the mailinglist was confused by Marc's tagged address
(since neither Roland's nor my answers to this thread have reached me
through list or are on http://lists.jedsoft.org/lists/jed-users/2016/),
I'm reposting mines:

Yes, it defines such variables making clever use of get_termcap_string,
see https://github.com/hankem/jed/blob/master/lib/keydefs.sl
(which is JED's current master branch; just directly viewable online).

Nothing else. I either had once a terminal where this didn't work out of
the box -- or just put it overzealously... Anyways, I don't remember. ;)

I have never had a deep understanding of terminals and their sequences,
but assumed that this very represenation of a key may change between
different terminals (or operating systems, or whatever?) -- which is why
keydef.sl's get_termcap_string magic is the sustainable way to go.

Schöne Grüße,
