Jeez - sorry for not answering sooner. I spend all my time in the "General" area...
To be a bit more clear, in Photoshop you have this lasso tool where you just touch down with your stylus and wherever you go, it draws a lasso. Photoshop does have a click, move, click, move, click version as well. But for me the click-hold and drag is the best. In the Photoshop CS6 lasso options, it's the top one. Just above polygon lasso, although that would be cool too.
Hopefully that makes more sense.
