Until now, you can use the “Toggle Change > Colors” push button, e. g. add it with Settings -> Configure Toolbars to the > toolbar. The only problem is that it doesn’t toggle itself, only the > viewport toggles. Thanks that was really helpful, You are right the problem with shortcut was persistent because I never close Okular I kept it always opened with all my needed pdf files, but after closing all my files and restarting the shortcut is working again. And I also added “Toggle Change Colors” push button to toolbar and it seems to work really good. You saved me a lot of time because I always keep Okular colors to White (foreground) on top of dark gray (background) to avoid hurting my eyes especially at night, but for some files that have technical drawings I need to always temporary disable the changed colors to see correctly its contents. Really big thanks to you :) -- You are receiving this mail because: You are watching all bug changes.
