I'm looking for a way to automate the selection of adjacent faces through a script, which I could then assign to a hotkey in Blender.
I come from Maya, which doesn't have this ability either, but I was able to make a Mel script that does this type of selection for me with the following steps.
1- Store the current selection of faces in a variable.
2- Expand the selection once ("ctrl +" is the blender equivalent).
3- Subtract the faces I stored at the beginning from my current selection.
4- The polygon border remains!
Is there a way to achieve the same thing through a blender script, or maybe there's an existing blender command I'm unaware of? Even if there is some methodology for doing this in blender, the one-key-press automation is my ultimate goal.
