Also, added few features to the new version of Google document editor:
Faster find: press Ctrl+F (?+F on Macs) you'll see a drop-down box where you can type word or phrase you're looking for in your doc. As you type, all matches in the doc will be highlighted and you can press to jump to next match. For more advanced find options or if you want to replace text, you can access full Find and Replace dialog from Edit menu.
Headings in the toolbar: added Paragraph Styles to toolbar to make it much easier to quickly apply headings to things you've selected in your doc, or to change your selection to normal text.
Bookmarks in the link dialog: If you go into that dialog, you'll see a list of all the bookmarks in your document and the snippet of text that's near that bookmark.
