I want to open up my G3 iMac keyboard to clean out the dirt that's
fallen to the underside. Where would I find the kind of hex
screwdriver needed to open it up, and what size should I look for? (I
bought a generic toolkit, and it has a hex screwdriver that's pretty
small, but not small enough.)

Apple uses metric threaded screws for its internal board and sled
mounts, so I would imaging that the hex bit needed would be a metric
size also. Search the internet for metric hex bits, and you'll get a
boatload of suppliers to choose from, with allen type drivers being as
cheap as 10 cents. It will make the 3-4 dollars shipping seem ludicrous
by comparison. I've seen metrics as small as .5 mm, or 20 thousandths
of an inch (0.020 inches). Perhaps a local hardware store or
electronics/computer surplus or supplier can sell you what you need
without the shipping charge.

I don't have that keyboard so I can't say for certain, but as a rule,
Apple uses Torx fasteners rather than hex screws. You can obtain Torx
screwdrivers in sets from sizes T1 to T6 (one of which should fit your
situation) from a variety of sources.

The smallest Torx screwdriver they make starts at T5 or T6. They
don't make a T1, way too small. The hex screw on the Apple keyboard is
included in the standard Craftsman hex key set, a .050 key. It's the
smallest one of the bunch.

Damn, they's small. Here's a good site for detailing on how to take
apart the Apple Pro keyboard.

Home depot sells an excellent Mini screw driver and hex driver set for
about $5. We use them for service here. Excellent quality. In the tool
section, by the other mini type (cutters) tools. Easy to miss. They
have torx sizes from 1or2 up in the set, which all fit in the handle.
Grab the magnatizer/demagnitizer which is in the same area while you
are at it. Simply slide the driver through it, and work is a breeze.
