Lightroom - How To Hide/Show Mask Layers

When you are doing multiple edits with Filters, you sometimes find that the previous mask pins get in the way. It's an easy fix, just use the keyboard shortcode H to toggle between hiding and showing the pins.

It is difficult to forget this shortcode, but if you prefer the long route, there is a little toggle selector at the bottom of the Loupe View, just change 'Show Edit Pins' to 'Never' to hide the mask pins, and then back to 'Auto' to show them again.
