P: Easier Way to Release Angle Tool

When using the Angle tool in the Crop overlay, it’s really easy to mess up the line when lifting your finger off a trackpad. It moves the cursor slightly and throws off the straightening.

I would be elated if there was a way to finish the line by pressing a key (like Shift, Enter, whatever) instead of lifting off the trackpad. This would make straightening way more accurate and less frustrating, especially for laptop users.
