I have used Sumatra PDF Reader quite a long while, but only as a reader. Today I downloaded the PDF User's Manual for my new Nikon DSLR camera. For the first time, I tried to get Sumatra to let me: (a) highlight key text in yellow, AND (b) copy blocks of text for pasting into personal notes that I take with me on photo shoots. Mean old Sumatra refused to let me do either. (a) No highlighting allowed. (b) I could "select" text but, when I right-clicked it, the "Copy" command was grayed-out & dead. So I then tried FoxitReader. It also would not let me do those actions. I suppose that's why they call them "Readers" -- perhaps to stop folks from plagiarizing & other nasty things. Q-1: Is there a way to get Sumatra to allow me to copy text & highlight? Q-2: If Q-1 = "No," is there a PDF app that WILL let me highlight text and copy text? (I hope there's a freebie but, if I have to buy the app, I will -- if it isn't too radically expensive.) Any & all comments will be hugely appreciated.
