If you're a serious iTunes user, you're probably well aware of the Get Info window (File -> Get Info, or press Command-I). The Get Info window in iTunes contains seven tabs--Summary, Info, Video, Sorting, Options, Lyrics, and Artwork--that give you fine-grain control over all of those options for a given track in your library. But again, if you're a serious iTunes user, you doubtlessly know all this.
What you may not know about this window is that you don't have to reach for the mouse to change tabs--instead, you can just press Command-1 for the Summary tab, Command-2 for the Info tab, Command-3 for the Video tab, and so on. For me, this is a much quicker way to get to the various tabs, instead of moving between keyboard and mouse. (Once a tab is active, you can use the Tab key to reach the various fields on that tab.) If you're running iTunes 8, this same trick works in the new Multiple Item Info window--Command-1 is the Info tab, Command-2 the Video tab, and so forth.
As an added bonus, you can even change tracks with the Get Info window open, and without reaching for the mouse to click on the Previous or Next buttons. That's because--even though they're grayed out in the Controls menu--the keyboard shortcuts for previous (Command-Left Arrow) and next (Command-Right Arrow) song work with the Get Info window open.
Finally, it seems the iTunes programmers really, really liked these Command-number key shortcuts, as they also enabled them in iTunes' preferences. That's right; you can directly select any of the sections in iTunes' preferences via the keyboard. After opening iTunes' preferences, you can, for example, jump to the Sharing section by pressing Command-3, or to the Apple TV section by pressing Command-6. I've tried this same trick in many other Apple programs (Mail, Safari, iCal) that feature tabbed preferences, but it appears this particular trick only works in iTunes.
