This links is a link to a post by Tigerears from November 2011, and early this week I somehow came across this excellent tutorial. I feel a bit noobish that I didn’t know about the ALT key earlier ! Tried it out last night and it saves so much time ! So here we go :

Does anyone know whether exploration is still worth it ? I am reading some mixed reports on the Forums. I trained up the skills needed for it a while ago, but never got around trying it out.
