The European pricing article in TidBITS-168 prompted a tremendous response, which I've forwarded in part to various groups, where I hope the discussion will continue. It's difficult and time-consuming for me to repost comments so please, consider posting comments to a group before sending them to me personally. If you do send them to me, please note if you DON'T want me to repost them anywhere (I avoid anything that's obviously sensitive, but I'm not omniscient).
File Email with a Key in Apple Mail
In Mac OS X 10.4 Tiger or later, you can use the simple and fun MsgFiler Mail plug-in to file Mail messages using keyboard shortcuts.
New in Apple Mail 4 (the 10.6 Snow Leopard version), to assign a keyboard shortcut to any mailbox on the Move To or Copy To submenu, you can also open the Keyboard pane of System Preferences, click Keyboard Shortcuts, and select Application Shortcuts in the list on the left. Click the + button, choose Mail from the Application pop-up menu, type the name of the mailbox in the Menu Title field, click in the Keyboard Shortcut field, and press the keystroke combination you want to use. Then click Add.
