When I am typing I want to be able to use the compose key to get at "dead" characters, if I press the compose key simultaneously with the key I want I can toggle dead mode, for the next key I press.
however, if I press the compose key alone, all subsequent keypresses give me their level 2 symbols. I don't know how to go back to normal key symbols... this compose mode seems to be locked on forever.
As an example in below, the first line is typed "123..." then I press alt-gr by itself... then I type "123..." again but now I get all the compose versions and not the normal numbers. (this is a French keyboard in this example)
normal typing 1234567890 gives me 1234567890
I press alt-gr once then 1234567890... gives me &é"'(-è_çà
now the only way to go back to 1,2,3,4,5 etc is to press shift+1 etc
The keyboard is locked into the compose mode and I need to restart to get it out of this mode, (or change it to a different language).
to be clear, it seems that on my keyboard entering this "compose mode" is a permanent effect, and lasts for longer than just the subsequent keypresses, I want it to turn off after the next keypress.
