Thanks, What does it mean to be a filter or not. I would have said inverting colors is one of the basic filters. The Layer > Invert does act like a filter, once used you will see the Repeat filter in the Filter menu as seen in my first screenshot. I think It's all alone in the Layer menu nothing related can be found there. I'm not going to argue to remove it from the Layer menu but an alias at the Filter > Color menu would have saved time and made it discoverable within the program.

After some searching on the internet I found the shortcut for invert colors to be Ctrl+I But I have yet to find the feature looking through the menus. Under filters I found "Repeat Invert" after I had pressed Ctrl+I So it appears that invert is a filter but the filter itself is not in the filter menu.
