Some useful Mac software tips
Emacs editing keys work in a lot of places in Cocoa apps. Try them in Safari TEXTAREA boxes, or iChat’s text entry area! This is a great feature for me, since those keys are practically hard-wired in my brain. Note that Ctrl-K and Ctrl-Y will in fact Do The Right Thing, and don’t affect the clipboard (but the “kill ring” isn’t implemented, and the “kill buffer” only works within one app).
Somewhere along the way, iTunes got the ability to use Playlist is/is not X as a Smart Playlist criterion, and I didn’t know this until recently. This lets you get Boolean nesting, if you can put up with the intermediate playlists. Now I have a playlist of all the 4-star songs not played in 70 days and all the 5-star songs not played in 14 days, shuffled together. Yay!
Lukas also pointed out that you can use this feature to get a playlist of all the unchecked songs. First, make a playlist of all the songs added after 1901, “limit to checked songs”; then make another playlist, “Playlist is not” the first playlist.
