Do you mind if I ask how you came across this? I'm too lazy to check Wowwiki, but it would be best for something like this to have documented credibility. Further questions:

* I noticed you bound left click - "bind F6 CAMERAORSELECTORMOVE" What do you use left click via keypress for?
* Is first person view the best practice for this? I assume it works because your character is inside the corpse so a click on the corpse is likely.
* How about top down view? That might be better practice for players with different heights.
* In order for this to work, do you have to place the mouse cursor in a specific location on the screen, or is the mouse click automatically generated in the center of the screen or something?

ps - Are you on a fax modem or something?
