Blogger has several keyboard shortcuts you can 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 + p = Publish Post
* control + s = Autosave and keep editing
* control + g = Indic transliteration
