Peek-a-Boo, I See Your CPU -- Clarkwood Software's Peek-a-Boo, one of my favorite utilities under Mac OS 9 and before, has now been rewritten for Mac OS X. Peek-a-Boo is a process watcher; it displays the applications and Unix processes running on your computer, along with lots of data about them. Unix geeks and Mac OS X mavens may be tempted to dismiss Peek-a-Boo as merely a graphical front end to tools like "top" and "ps," or a partial duplicate of Apple's own utility Activity Monitor. But graphical front ends are good, and Peek-a-Boo does make it easy to do tricky things such as constructing a running graph of an application's CPU usage over time, or changing an application's priority ("renice"). It would be great if Peek-a-Boo could do even more - for example, it might show an application's open files ("lsof") or disk activity ("fs_usage"), graph memory usage over time, and so forth - and it's a pity that Peek-a-Boo is itself something of a CPU hog. But users may still find it a useful addition to their bag of Mac OS X tricks. Peek-a-Boo is $20 ($10 for previous owners), and a fully functional demo is available as a 565K download. [MAN]
File Email with a Key in Apple Mail
In Mac OS X 10.4 Tiger or later, you can use the simple and fun MsgFiler Mail plug-in to file Mail messages using keyboard shortcuts.
New in Apple Mail 4 (the 10.6 Snow Leopard version), to assign a keyboard shortcut to any mailbox on the Move To or Copy To submenu, you can also open the Keyboard pane of System Preferences, click Keyboard Shortcuts, and select Application Shortcuts in the list on the left. Click the + button, choose Mail from the Application pop-up menu, type the name of the mailbox in the Menu Title field, click in the Keyboard Shortcut field, and press the keystroke combination you want to use. Then click Add.
