BlogMore v2.9.0

After releasing blogmore.el v2.6 this morning, I noticed something about the post: the text that was marked up with <kbd> wasn't really standing out as keys. In blog posts, as in documentation, if I mention the name of a key, I like to mark it up with <kbd>. Ideally, with such markup, the styling of the page it's being used on will make it clear that it's supposed to be read as a key.
