In my LaTeX writings I always use the same abbreviated commands, since many years. For example, I use "\z" for "\langle" and "\x" for "\rangle", or "\fr" for "\displaystyle\frac", and so on..

Is it possible to implement a solution that remembers the user's own additional LaTeX commands somehow? (Or maybe such feature does already exist?)

    $\begingroup$ What? \z \x? But then you don't get to say "langle rangle" in your head whenever you generate a subgroup. $\endgroup$ – Alexander Gruber Mar 20 '13 at 21:10

  • $\begingroup$ I have asked about solutions which could serve as a workaround if this is not implemented: Is there some way to include some default text quickly in a post? $\endgroup$ – Martin Sleziak Feb 14 '20 at 16:18
