The Rotate View tool is extremely helpful when painting, drawing, or doing anything in Photoshop that benefits from rotating a document on the screen (allowing more natural hand positioning and movement) without actually rotating the contents of the document.
The Rotate View tool works very well in tandem with “Spring Loaded” cursors. Instead of tapping ”R” to select the Rotate View tool, hold the “R” key to temporarily access the tool. Then, when you release the key, you will automatically be returned to the selected tool. For example, if you are drawing a path with the Pen tool but need to change the rotation of the view – press and hold the “R” key, drag to rotate the view, and when you release the “R” key – you are back with the Pen tool, ready to continue drawing!
Double click the Rotate View tool to reset the view or, with the Rotate View tool selected, tap the Escape key to reset the view. Using the Options bar, you can also choose to rotate only the active document or all open images (Rotate All Windows).
