I'm a huge fan of Apple's Shark. One of its cool features is the "ASM Help" button shown in the lower right corner of the window when looking at the disassembly of a sampled function. Selecting a instruction and pressing the button brings up a compact reference of assembly instructions. I like to look things up in it because I'm curious, rather than because I have any particular use for the knowledge contained therein, but I like having it handy.

Now, what if you want to look stuff up some time other than when examining Shark results? The assembly reference(s) are actually stand alone applications, but they're hidden away in a slightly odd place: Take a look in the /Library/Application Support/Shark/Helpers, though, and you'll find them.
