I know that this is not quite what you are asking for, but just in case, the “obvious” did not happen to you (or future visitors to the question), assuming that you downloaded the module with an annoyingly cumbersome name, for example
import LaTeXStrings
and you don’t want to introduce LaTeXStrings all the time just to learn about its accessibles, i.e.
LaTeXStrings.[TAB]
you can simply assign the imported module as a whole to another variable, i.e.
const l = LaTeXStrings
, , , l.[TAB] LaTeXStrings.[TAB] :)
( , julia, , import LaTeXStrings as l...)
