====== Messing with keys ======
<style float-left>{{gravatar>yann.hodique@gmail.com}}</style>
Context : as I mentioned in a [[blog:2006:20060510_get_the_keyboard_you_deserve|previous post]], I use a slightly modified qwerty map, where parentheses and brackets are switched.
Quite recently, for various reasons, I came to use [[http://software.schmorp.de/pkg/rxvt-unicode.html|rxvt-unicode]] as a terminal emulator. 

Although being otherwise very nice, this little program used to suffer from an annoying feature, namely the builtin iso-mode. Actually, it's not the iso-mode itself that is annoying (after all, being able to compose rarely used characters does not hurt) but the fact that it is hard-bound to the control-shift combination.
There are at least 3 arguments against this choice :
  - such a sequence is easy to hit by accident
  - anyone who would like to use emacs in console mode is screwed
  - in any case, that feature should be an option

So I am very happy to hear that the default behavior has changed in the latest version, and that iso-mode is now activated only in the ''rxvt-unicode-ml'' flavor. I hope Debian will ship version 9.x soon.

Given that, the key handling in ''rxvt-unicode'' is still quite strange... Remember that I mentioned the switched brackets/parentheses ? This means that I have to hit shift to compose a bracket. As you may know, the default escape character for telnet (that enables you to close the session at the protocol level, for example) is ''^]'' (that is ''ctrl-]''). No need to say that with my configuration, iso-mode was a real annoyance regarding this...

Still, //without// iso-mode, the behavior is strange : hitting ''^]'' simply does not work when '']'' is not where expected (neither does it with ''rxvt'', but ''xterm'' is ok). Maybe it's related to my ''~/.Xdefaults'', but I can't see why :
<code>
rxvt-unicode*background: DarkSlateGray
rxvt-unicode*foreground: Wheat
rxvt-unicode*cursorColor: Yellow
rxvt-unicode*font: xft:Dejavu Sans Mono-8
rxvt-unicode*reverseVideo: false
rxvt-unicode*scrollBar: false
rxvt-unicode*saveLines: 5000
rxvt-unicode*reverseWrap: true
rxvt-unicode.geometry: 80x25+20+20
rxvt-unicode*fullCursor: true
rxvt-unicode*scrollTtyOutput: off
rxvt-unicode*scrollKey: on
rxvt-unicode*titleBar: true
rxvt-unicode*color12: #84bdd2
</code>

Anyway, I've just accidentally discovered that ''^}'' works ! (I mean, in ''rxvt-unicode'' **and** ''xterm'')
As far as I know, this is undocumented feature, but I couldn't care less... I'm at the point where I don't understand the problem, nor the solution. Time to sleep I guess...
