I really really need someone to explain text to me.

I create a box, write in it, and then it seems to become an unmodifiable, uneditable, uncolorable entity. I select it with the select tool and nothing selects to edit. I select it with the text tool and all that wants to do is create another line of text.

How does a person go back to a box of text and change it or select a font or color or anything? I presume that it's possible to actually edit text, but the method is definitely unfigureoutable and if it's in the help files it's cleverly hidden under undescriptive terminology.

Thanks
