Normally when you click on the Brush tool, a palette appears somewhere on the screen and one of the many palette options is Brush Tip Shape. But I've seen a Photoshop tutorial on Pluralsight where the person who was painting opened the Brush Tip Shape right at the brush position on canvas, probably after pressing some hotkey. This way it's very close to the brush and you can adjust the brush tip direction quickly. But I can't find any information about such hotkey. So, how to open this palette on the fly?
