I have two monitors and one monitor could be showing text in an app like a text editor, pdf reader, help file, web page etc.. Then I need to change focus to the app on the second monitor. Even if I have highlighted some text to remember my last position in the document, the highlight is lost when I switch focus to the app.
I am looking for a system app or tool which allows me to highlight (or paint over) any text in any app and it stays fixed even if the underlying app loses focus. I am using Windows 8.1.
Any recommendations?
