So instead of pressing x to get to normal view again, we could for example press y and get that particular page black on white again but with maximum contrast.

Then on another page repeat that all over again, press x for night mode then y for inverted maximum contrast black on white.

Thanks a LOT!
My problem was that I haven't pressed the keys Shift+X simultaneously.

It can be good idea to write to the help page which shortcuts should be pressed simultaneously and which sequential.
