“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.
I’m not sure why but I’m on a command line kick lately. Not just the Tron Legacy style for Terminal but I’ve now begun using iTerm2 as my Terminal application of choice. I have it in a second Space on Mac OS X fullscreen with 3 shells running.
The first shell is 50% of the screen split vertically. The other two are each 25% of the right-side of the screen split horizontally. This way I can edit files in the left hand pane via Pico or Vim, use Git in the lower right-hand corner and be SSHed into my server in the top right. Here is a screenshot.
The inspiration for this came from constantly seeing my fellow Viddler team member Todd Troxell rock the command line exclusively. Dude is hardcore and seldom uses any UI save for the Web itself.
