I think I've seen this on some other and it made things a bit quicker. Alias as in you can use #1 or whatever else that would be economical to use the command #who.

Set with something like #alias 1 who

Being able to do something like that instead of typing out transfer would be a saver too.

Workaround (for now!?)
type #tr and hit tab, fair chance you get /transfer. Otherwise keep on tab-ing.
