Dodge/Burn tool question

[conrad2k]

I have used the Dodge and Burn tools on the iPad version for a while and have always wondered how the little color wheel with a lock in the middle is used, and the gray target with the pen in the bullseye.  What's that for? When I tap my Apple pencil, or finger, on them, nothing seems to change with the tool's performance other than they get a gray highlight around them.  I've learned a lot from videos, but none seem to go through each tool with a detailed explanation.

From the built-in Help:

Quote

Protect Hue—when selected, the colour tone remains faithful to the original hue.

Force pressure to control size—Toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.

My problem with the built-in help, not just for this but also for quite a few other things that explain the functions on the context toolbar, is it never clearly shows which is the enabled & which is the disabled state. Particularly on my 9.7" iPad, the icons in the help topics are so tiny it is hard to tell if they are shown on a grey or black background, much less which state that is supposed to represent.

This may seem like a minor thing, but help topics are supposed to cover that kind of info -- otherwise they are of no help if that is what a new user is confused about.
