Navigation, have link retain focus , actionscript?

okay i have a series of standard navigation buttons.

[COLOR=Gray]link 1 link 2 link 3[/COLOR]

these buttons load certain movie clips and what not. okay so the deal is i have them have the standard color change on rollover but what i want when the click on say link 1 is for it to change and stay like black for instance to represent what section the user is on.

link 1[COLOR=Gray] link 2 link 3[/COLOR]

basically its a navigation thing letting people know what section they’re on. it seems like a simple thing but all ones i’ve got to work are hacks and aren’t efficient at all.

is there a way to do this using global variables and a function instead of a long *** list of if then statements?
