Custom Shorthand: Include Description of Order Priority to avoid Parameter Overlap Conflicts

[ArgensVentus]

In custom shorthand, if I were to make the following shorthands:

->:::\xrightarrow[#cursor]{#tab};
<->:::\xleftrightarrow[#cursor]{#tab};

the shorthand $<->$ will always be ignored to generate <\xrightarrow[#cursor]{#tab}.

This is fixed by switching the parameter order to be:

<->:::\xleftrightarrow[#cursor]{#tab};
->:::\xrightarrow[#cursor]{#tab};

but I would recommend including a line under the description of "Custom Shorthand Parameter" to indicate that the list order does matter
