Program for fonts

Alrighty, quick question... I've seen talk of this, the problem is I forget what it's called... is there a program that allows me to see what a certain font looks like? Whenever I'm using Adobe Photoshop 6, I only have a list of the font names and it takes me ages to figure out what each one looks like and before I'm done finding the proper font and writing the text for my icon, I'm pretty sick of it! lol

Thanks! ♥
