Sleeping Floppies -- Rich Wolfson <firstname.lastname@example.org>, author of The PowerBook Companion, passes on this helpful PowerBook hint. Apple tells you to shut down the PowerBook 100 before attaching the external floppy drive. The reason for this is not because of electrical danger, but because even though the driver for the floppy drive loads from ROM, the PowerBook 100 sets a bit at startup that indicates whether or not a floppy drive is attached. If you boot without the floppy drive attached, that bit thinks there is no floppy drive, and attaching the floppy drive after the fact won't work. So, follow this procedure. Shut down the PowerBook, attach the floppy drive, boot the PowerBook again, and when it wakes up, put it back to sleep. You can now safely remove the floppy drive, and when you want to use the floppy drive again, assuming you haven't rebooted, you can put the PowerBook to sleep and attach the floppy again. The Duos are even neater; you can attach the floppy at any time to a sleeping Duo because it has the floppy driver in ROM and also includes special docking features that allow you to attach a floppy drive (via the floppy adapter or MiniDock) when the Duo is asleep. Never attach an external floppy to any PowerBook while it is awake!
Springy Dock Tricks
If you drag a file and hover over Dock icons, various useful things happen which are similar to Finder springing. If it's a window, the window un-minimizes from the Dock. If it's a stack, the corresponding folder in the Finder opens. If it's the Finder, it brings the Finder to the foreground and opens a window if one doesn't exist already. But the coolest (and most hidden) springing trick is if you hover over an application and press the Space bar, the application comes to the foreground. This is great for things like grabbing a file from somewhere to drop into a Mail composition window that's otherwise hidden. Grab the file you want, hover over the Mail icon, press the Space bar, and Mail comes to the front for you to drop the file into the compose window. Be sure that Spring-Loaded Folders and Windows is enabled in the Finder Preferences window.
