I am looking for a way to scale/transform a Photoshop layer using the keyboard only. Similar to the way this is handled in InDesign would be ideal, with a dedicated keyboard shortcut I can assign (such as Command + , and Command + . in InDesign for Mac, if I recall the shortcut correctly).
One possible workaround solution to this would be to be able to highlight the first Scale field in the Options Bar (or any field in the Options Bar, actually) and just tab over to the Scale fields. But I've not been able to figure out a way to do so.
