A clever solution to something that has always bugged me about Photoshop. As the article explains:
When nudging vector points, Photoshop exhibits some strange behaviour, linked to how far you’re currently zoomed in. At 100%, nudging using the arrow keys will move your vector point exactly 1 pixel. At 200%, nudging moves the point half a pixel. At 300%, it’ll move a third of a pixel.
This behavior results in Photoshop mockups that often have blurry, anti-aliased edges and corners, which makes the design in question look less crisp and precise.
