Behavior:

1. Load Safari 5.0 on mac.
2. Press command+f to search for some text.
3. Type something, and find it on the page.
4. Hit esc to cancel the search.
5. Irritatingly, get word completion menu rather than canceling.

Is there any way to make esc cancel the search, like it used to with Safari 4.0, instead of pulling up a word completion dialog? It's very annoying. Failing that, what's the best way to cancel the search with the keyboard?

Note: this also happens in any text field, the search box, the location bar etc.
