Virtual key-codes

Anybody who's ever needed to work with virtual key-codes—especially to program a hotkey—has had the problem of looking up the key-code for a specific key. The usual solution is to fire up Peter Maurer's Key Codes.app and press the key, but wouldn't it be nice to look it up in a handy table that you could print out?

There actually is such a table, but it's well-hidden in the Apple documentation. Mac OS X uses the same virtual key-codes that it used for the legendary Apple Extended Keyboard. Thus, the table in Inside Macintosh: Text still applies.

The problem is the asstastic low-resolution JPEG scan of the table that Apple provides in the online version of IM:Tx:

Good luck with that!

So I did some poking. It turns out that there is a PDF version of IM:Tx on the ADC website—complete with a vector, rather than raster, table. Unfortunately, opening a PDF and jumping to figure C-2 is no easier than firing up Key Codes and pressing the key.

So here's a handy-dandy crop of the PDF (with attribution added). Because it's a vector image, the key codes in this version should be clearly readable at any resolution. Here's what it looks like:

In case you're wondering, I cropped it by copying the figure in Preview, then pasting into Lineform, which enabled me to add the attribution under the figure heading.

In a previous version of this post, I provided a 600 dpi PNG version of the key-codes table. In making that one, Lineform also enabled me to export to PNG at 600dpi rather than 72.

UPDATE 2008-11-29: Replaced the PNG image with a PDF document.
