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?)

\x
? But then you don't get to say "langle rangle" in your head whenever you generate a subgroup. $\endgroup$\displaystyle\frac
you could use\dfrac
