Capturing and sending keys {Esperanto}

[AJK]

Hello there!

I've been googleing yet, and suppose it's hopeless to try, but better ask it...

I want to write a program which turns Cx to Ĉ, cx to ĉ et al WHILE
TYPING. (i.e. converting Esperanto x-system to real hats, for those
who know about this.) Therefore I though will need to capture the last
2 typed characters (from any application), send a double backspace and
after that send the correct letters (back to the same application)...

However, it seems inpossible to capture those letters, and maybe to
send them too...

Or am I wrong?

Greetings,

LaPingvino
