I am drawing a mask on a photo and I would like the pen tool lines to be invisible. I know I can change the color of the line from its default yellow color, but I would like to be able to make them invisible.
When drawing the mask the line gets in the way of the fine tuning of my edges of the mask and I need to see the photo itself and not have the pen line get in the way of my view.
Ideally it would be a keyboard shortcut where I can turn the visibility of the line on and off.
There's a switch for mask visibility at the bottom left of the comp window (third goodie from the left or just to the right of your screenshot) or you could use the keyboard shortcut Ctrl/Cmnd + shift + h. You can't manipulate when the mask is hidden, but you can see what you've got. The keyboard shortcut hides layer frames also.
