Thanks, mrcheeks. Er, but, then what?
I right click on the desktop. create new > file > link to application. So far so good.
Next comes a dialog box. The General tab, even I can figure that out. Permissions I leave alone. But I get hung up on the Application tab.
I assume that the box titled Command is crucial. This is where I put the actual full name of mozilla, right? So.... how do I find out what that is? If I click the browse button, I get all my files, but not program files. I'm sorry, I know I'm sounding like a complete fool. Oh! It might be because I AM a complete fool!
