lol how u mean custom texts ?? but u can jus basically cut them out and use them (render them) and then use it in ur document. If not download the font.. install it and then use the Font Tool.
What text are you trying to put in there? Link us to the site you are trying to copy or cut from. Might be as easy as just d/l the font.
He wants to know how to install fonts to his computer I think the answer is already on this forum. Just search.
download that font, and put it in C:Windows/Fonts. Then restart your PS and then select the font from the list.
