Currently, I'm able to get a bookmarklet that will copy the document title into the subject area; however, I cannot get selected text, OR the page URL to hit the entry text area. I've tried six ways from next Sunday, including every encoding trick I can think of. Whenever I attempt to get it to load data into the text area, it b0rks and doesn't even load the subject. Here's what I have so far:
If you want to use it drag this link
to your bookmark bar.
Perhaps someone can expand on that.
Subject area is named: subject
Entry text area is named: draft
At least it's quick access to the update.bml page with the document title already in place. heh.
Perhaps someone else can manage something better. If you had asked for something in PHP... *shrug*
