Found this neat little trick today, not sure if it's on here(couldn't find it in searches) but here it goes!
Seems that if you have a wizard and use the Familiar ability to have the little pet following you around, if you hit "T" for town portal it will cause your pet to shoot. It's not super amazingly useful but the only thing that is really cool about it is the fact that it will shoot and it won't stop you from running - could be somewhat useful for kiting (Yes there are better ways).
If you really need step by step instructions here:
1-be a wizard
2-summon your Familiar
3-run around pressing T
Note: This will not work in town since you can't use TP in towns.
