Blogger Help : Can I use keyboard shortcuts while posting?: "Blogger has several keyboard shortcuts for use while editing posts. They definitely work in Internet Explorer 5.5 /Windows and the Mozilla family (1.6 and Firefox 0.9 ), and might work in other browsers. Here they are:

* control b = Bold
* control i = Italic
* control l = Blockquote (when in HTML-mode only)
* control z = Undo
* control y = Redo
* control shift a = Link
* control shift p = Preview
* control d = Save as Draft
* control s = Publish Post"
