Use multiple unique undos in Apps
Here's one I stumbled on by accident: I was getting ready to send an email to someone, but at the last second I decided to send it to someone else, so I changed both the recipient and the message accordingly. Then I changed my mind again, but instead of laboriously retyping the entire original message I just hit command-Z in the message body until it was restored, as expected. Then I clicked in the recipient field and hit command-Z on impulse, and the original recipient was restored. Just for fun, I placed the cursor in the Subject field, and found that it too had its own unique Undo queue. Bonus: Each field is multiple-undo-abled.

I haven't tested to see if the same holds true for other apps with multiple fields, but as Undo is usually global rather than local, I thought this was a tip worth mentioning.

It should work that way in any Cocoa app. Cocoa text views basically get undo for free.

If it is true that Undo comes for free in Cocoa applications, how come Undo does not work in Safari textedit areas on web forms, in the URL address area, or bookmark name and URL editing?

Wishing it would work....

the multiple undo also works with 'deleted' mail messages, ie undo move to trash
