(31) Dragging a document onto an application icon launches the application and opens the document. You can use this technique with ResEdit to open the resource fork of any file.
(32) If you need to find out exactly how much memory an application is using, turn on Balloon Help and point at the thermometer in "About This Macintosh."
(33) If you hold down the option key while switching to another application (via the application menu or by clicking in its window) the Finder hides the application that you switched out of.
(34) The functionality of the old Drive button in the System 6 Standard File Dialog box can be achieved in System 7 by pressing Command-LeftArrow or Command-RightArrow.
(35) Font/DA Mover version 4.1 (which is System 7 compatible) does not ship with 7.0. Version 4.1 is available on AppleLink, other electronic services, and from dealers. Older versions will not launch from the Finder 7, and if you use a launching utility like DiskTop, they will not work with TrueType fonts. You mainly need Font/DA Mover 4.1 to install the WordFinder Thesaurus DA into Word 4 or MacWrite (hold down option while clicking the Open button in the Font/DA Mover to open Word or MacWrite) for WordFinder to work.
(36) To quit out of an application immediately and awkwardly, hit command-option-escape. After using it you should restart. On a non-ADB keyboard I hear that command-option-tilde does the same thing.
Opening a Folder from the Dock
Sick of the dock on Mac OS X Leopard not being able to open folders with a simple click, like sanity demands and like it used to be in Tiger? You can, of course click it, and then click again on Open in Finder, but that's twice as many clicks as it used to be. (And while you're at it, Control-click the folder, and choose both Display as Folder and View Content as List from the contextual menu. Once you have the content displaying as a list, there's an Open command right there, but that requires Control-clicking and choosing a menu item.) The closest you can get to opening a docked folder with a single click is Command-click, which opens its enclosing folder. However, if you instead put a file from the docked folder in the Dock, and Command-click that file, you'll see the folder you want. Of course, if you forget to press Command when clicking, you'll open the file, which may be even more annoying.
