Continuing:
 * Shortcuts - we plan to make a list of those available.
 * Advanced wikitext/HTML stuff like code, divs etc. are indeed not available from toolbar buttons at this time. "Preformatted" should be available from the format dropdown though.
 * "Tab" functionality - we intentionally kept the normal editor function of switching to the summary box when you press tab (by user request). You can still use the arrow keys to move around table cells.
