Is there a way to make emacs expand abbreviations as soon as I finish typing them, rather than having to use a key combination, tab, or space?
For example, I want "`a" to expand to "\alpha". It would be nice if it could expand as soon as I type the "a".
I have tried abbrev-mode, but I can't figure out how to do expansions without typing a space (or other expansion character) after the abbreviation. The EmacsWiki explains how to prevent the expansion character from appearing after typing it, but that's not what I want. I also tried yasnippet, but it requires a trigger key, as far as I can tell from the documentation.
My specific motivation is to reproduce Vim-LaTeX-Suite macros, similar to this more general question asked here before.
