There is a dedicated site for software recommendations here on Stack Exchange but I'm not sure people there may know much about something like CDLatex.
I'm looking for a Latex IDE for Linux which has shortcuts like those of CDLatex, e.g. you press `z and you get \zeta. CDLatex is the main reason I use Emacs (in addition to its uncluttered interface). However recently I've had problems with either bugs or "misconfigurations".
