If you keep the option key pressed while selecting Open... Nisus will use the Claris XTND technology if it is installed. And the good news is that there is a XTND Developer package available at ftp.apple.com that includes XTND and filters for MacWrite and MacWrite II. It's in the /dts/mac/tools/xtnd directory, but it's big, about 520K. The XTND file must be in a folder named 'Claris' inside the System Folder, and all translators goes into the 'Claris Translators' folder inside the 'Claris' folder." [This trick works in 3.06; I can't comment on previous versions. I think more translators are available from third parties like DataViz.]
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.
