Opera takes a litte messing with, as its bookmarks work a bit differently...(it offers you a start page of the Opera 'help' file...it is good to keep that handy as you play with it...LOTS of options)

feel free to ask/PM if you don't see exactly how Opera does things..*smile*

I think one of its best tricks is that the Q,A,Z & X keys, right under your left hand, will move you thru links and pages...X & Z are forward-back, and on pages like Mudcat, Q & A will zip you up and down to each hyperlink....
