My hot rogue macro:
#show Shadowstep /dismount /cast [nostealth] Stealth; /castsequence [stealth] reset=10 Shadowstep, Ambush, Cheap Shot;
Dismounts if mounted, stealths if not stealthed, then does a Shadowstep to Ambush. Cheapshot follows in case Ambush misses (it could happen depending on hit chance). Part of the reason I love this so much is that it works from the air -- you can be 100 feet above someone and as long as they don't run out of range while you fall towards them, you appear behind them and take no fall damage (it's also great for tagging mobs around unsuspecting campers).
See Set look alikes. :-)
