Most word processing and page layout software have the ability to create style sheets, that is, a digital recipe of text formatting which can be applied throughout a document to both save time and create consistency. Did you know you can do the same in Photoshop?
First, create the desired text using the Type Tool. While the Type Tool is still selected click on the little triangle next to the tool's icon at the top-left of the Options bar to view the tool preset. Select "Current Tool Only" and click the tiny arrow on the top-right and choose New Tool Preset. Give it a name and POOF! You'll see it appear as a new preset in the list.
The next time you want to use that style, just grab the Type Tool then choose your style name from the preset menu in the Options bar and you're good to go. You can create as many styles as you want.
