I need help with right clicking a character and having text come up!?

I have selectable characters in my map, but I wanted to have a way for the map to give the players a breif discription of what the characters can do when the player right clicks on them with the mouse. I created a region for the player to click in but unfortunatly I can't find anything in the WE that mentions the mouse or how to manipulate it in any way. I imagine what I want to do couldn't be that hard to implement, but I just can't find the right phrase in the triggers to do it. So basically I want the player to right click on a character and then have some text pop up telling a little something about the character he right clicked on.

Any ideas guys i'm stumped!? :(

Thanks for the help,
Sincerly,

I figured it out, I decided to go with the left click, just because it's a whole lot simpler than trying to use the right click on the character
