Hi Psygorn,

re:
> With this script one can select loop of edges?

It looks like it is set to select a boundary loop if you have edges selected before running it.


> How about edges that are connected to a face?

Looks like if you have faces selected it will select the edges of the face.


> I should assign a short key to this script, if I want to use it?

Yes set up a shortcut key under Options > Shortcut keys and copy/paste in the above script for the "command" part of the shortcut key.
