In Linux Console, is there a way to make hitting a dead key twice print the corresponding dead character on screen? as it is the case in X11?

For instance I want the logical ^^ sequence to send a circumflex '^' character to my TTY. Currently I have to do ^SPACE in Linux Console, which I am not used to after many years in a X environment.

I am using the kbd stock fr-bepo keymap, which maps the dead_circumflex keysym to the Y physical key (keycode 21) of my AZERTY keyboard.

After reading the man keymaps(5) page, I tried adding the following rules in my modified keymap

keycode 21 = dead_circumflex # already set by 'fr-bepo'
compose '^' '^' to asciicircum # added by me

but this doesn't seem to work as expected..

This would only make the logical COMPOSE^^ sequence to work, but this would be worse than the stock ^SPACE sequence..

I think this is due to the fact that dead_circumflex is equivalent to a logical COMPOSE^ sequence, so hitting twice my Y physical key would generate the logical COMPOSE^COMPOSE^ sequence instead the COMPOSE^^ I was expecting.

Of course I can't just map the physical Y key to the plain asciicircum keysym because I also need the logical ^E sequence to generate a 'ê' character (often used in french).

  • @ThomasDickey this is actually a really good topic! But my problem seems really to be specific to the repeated dead keys sequences.. – ovmjm Oct 27 '18 at 23:30
  • I really don't get it: Why is not possible to simply type one ^ as the ^ ?. And: why not use "dead keys" ? Note that there are (at least) three methods to type accented characters. The one you use seem to be only to use the compose key. The second is using "dead" keys in which you press the ' key followed by e to get é. The third (which I use) is to enable the AltGR (convert the right alt to it) key, press AltGr-e to get a é. – Isaac Oct 28 '18 at 22:28
  • @Isaac the stock fr-bepo keymap actually already uses dead keys. This easily allows to type ^e to get a ê. But this not allows to type ^^ (with the same keyboard dead key of course) to get a simple ^, I have to type ^SPACE which I'm not used to. In X11 ^^ is working very well. – ovmjm Oct 28 '18 at 22:42
  • Again: Why type anything else than a ^ to get a ^? – Isaac Oct 29 '18 at 12:36
