Don’t Click In That Field!
Those tiny little fields up in the Options Bar can really be a pain sometimes, especially if you’re trying to highlight a field, delete the current value, and type in a new one. Instead of doing all that, just click on the field’s name and Photoshop will automatically highlight the entire field for you. That way, you can just type in new values and it will automatically replace the old values. Great thing is, this doesn’t just work in the Options Bar; it works in many of Photoshop’s palettes, including the Character and Paragraph palettes.
