If It's someone I use a lot, I bookmark them in my browser. I have my main paternal and maternal lines bookmarked that way, usually with someone I can work from, either backwards or forwards. For example, I bookmarked my White great-great-grandfather, because from his profile I can easily get to my great-grandmother. I also pasted my entire Watchlist in a Google Spreadsheet. And, of course, you can search for them.
