Evernote is the favourite note-taking and organisation software for Lifehacker readers, and rightly so. If you use it right, it's a beast. But one common problem is that after a while, your tags don't help in searching for the right item, because they can also show up as regular words within your notes. The Alpha Efficiency blog has a cool workaround: add an X at the end of the word.
So the tag "idea" becomes "ideaX" and "note" becomes "noteX". The blog explains that not many words end with an X, making this an effective tagging system. They also tried hashtags, but Twitter has made that a no-go now.
Obviously you can change the letter x to any letter of your liking, but from my experience, this feels more natural, as there are not a lot of words that end with X. You are welcome to try letters to your liking. Mike Vardy is adding V at the end. Maybe capitalising the tagging letter could also be beneficial if you are tagging just a particular part of the note.
Of course, there's no reason to restrict this just to Evernote. If you tag items in any other note-taking or bookmarking system, you could use this little tip there too.
