Following up on my obvious love for Notational Velocity is this little nugget from Justin Blanton via Twitter. The latest build of Notational Velocity can actually handle bulleted lists in plain text using unicode bullets and some smarts.
Here is how you do it, again, via Blanton;
“Do [space][some bullet-type char (I use "•")][space][text][return] and you’ll get another bullet.”
That “dot” you see there can be found in about 1,000 variations using your Mac. The easiest one to key, in my opinion, is keyed using OPTION+8. So, simply key Space + OPT+8 + Space + Text + Return and you’ll be editing a list.
