It creates a popup menu of Players/NPC's by using your combat log, mouse-over, and/or minimap. You can 'left-click' the buttons to target or 'right-click' to target AND announce their position to a specified channel.
More detailed answer:
By using 'Sentry Mode' you will get enemy player targets to appear on the popup automatically if they do anything near enough to you that your combat log reports it. Also, the popup does more than just allow you to target and announce things. It can keep track of targets over time and adjust the background color fade to let you know which is more recently active (darker is higher priority). It removes dead targets (optional) and adds new targets as they appear. It will also update targetted and moused-over targets health (shown by how filled the colored bar is). It can keep track of all damage taken from enemies and you can also add enemy player targets to your own 'Hit List', which will give you extra warning if they appear on your popup.

Optional Files - Personal Sentry
Sorry, there are currently no optional files available.
v1.54b is now uploaded. This will be my final TESTED release as I will no longer have WoW after tonight. Hopefully someone will pick up the project as it will be difficult for me to enhance it any further without being able to test my changes.

If you have Sentry Mode enabled and the Sentry Filter set to 'ALL' then it would make them appear on the popup if they took any action that would harm you or your party and if they cast any buffs. It can't determine thier location relavent to yours though to warn you if they are moving in your direction.
