Have TextEdit Auto-Save

This may be something everyone who is an avid TextEdit user already knows but it is new to me and I have not seen it anywhere on the mac web sites. Go to TextEdit's preferences and select the Open and Save side of the dialog box about 1/4 of the way down you will see the preference to have the files autosaved every so often well for me i am going to pick every 30 seconds. Give this a shot and let me now how it works for you.
