Panning camera for players to start location?

Hi I'm VERY new here.. this is my first post on the forums and I was wondering is there a way to automatically move a player's camera to a start location when a page is loaded? I was looking all over for settings and stuff but I didn't see anything like what I'm thinking of. If there isn't a way to do that how do you suggest I easily relay to players exactly where to pan their screen so they can see the tiny bit of revealed area when they step foot into a dungeon? thanks! :D

(Moved to Specific Use Questions) The Ping function (left mouse button and hold) can also be used by GMs to move players to a specific location. Hold the Shift key when you click and hold the left mouse button.  - Gauss

oh wow thanks a lot Gauss!.. is there a place where i can read about tips and tricks like this somewhere? i kinda just jumped right in without any knowledge of anything.. so far it's pretty simple to figure out but no knows how many cool features im missing out on hehe
