I just realized that my previous post might have come off as sarcastic; it was absolutely sincere.
I have my own strange way of marking up my own songs after I've made my initial handwritten notes. If I think of two different words that might fit somewhere just right, I write one on the main line, and the alternate right above it. If the alternate wording would change the direction of the lyrics at another point in the song, I insert certain symbols at both places, etc. etc.
It's for this reason that I still do all of my initial song writing with paper and pencil. But I love it whenever the gulf between the flexibility of the pencil and the rigidity of the computer is narrowed in any way. So hurray for flexible note taking and stickies!
