Stenography with emacs

[carlmarcos]

I would like to write a conversion package to change english text to brief 
stenographic text.

For instance, modify `like` with `lk`, and `there` with `tr`.  But be able to 
revert back to the original.  Perhaps something similar to 
`prettify-symbols-mode` for tex and latex language.  As far as I am aware 
`prettify-symbols-mode` can only handle a single glyph replacement rather than 
multiple characters required for stenographic replacement.  Conversely, going 
back to the original tex commands, am bit unsure whether 
`prettify-symbols-mode` remembers the original text or simply does another 
replacement from the glyph.
