Tweetie for Mac lets you switch between the Timeline, Replies, Direct Messages, and Search panels of your account with Command-1, -2, -3, and -4, relatively speaking.
If you use more than one Twitter account in Tweetie, you can switch between them by using Command-Shift-Up/Down arrows. This means you can switch between any account, and any panel under each account, without touching your mouse.
Tweetie’s shortcut convenience extends even to its popup posting window: hit Command-Down arrow while drafting a tweet, and you can change the account that you’re posting to by arrowing up and down, then hitting Space or Return.
I noticed people discussing things amongst themselves on the site via comments, but I’ve never liked communicating through comments when I’m trying to have a conversation, so I took the next step and created a forum for the site! Facebook, although great for linking people, is incredibly lacking compared to what php/bb forums can do, so let’s see how creating an online community for the sanshin can do.
