Your Mac Life host Shawn King admitted that he normally glazes over when topics like multitasking are broached, but a good time was had by all while discussing all the things we think of when we say "multitasking" and how (or if) we'll see support for them in the iPhone OS.follow link
Copy Existing Filename to 'Save As' Field
While many utilities provide file naming automation, they're mostly overkill for those cases when you need to make small variations in file content while ensuring the documents group together in a "by name" list.
In the Save As dialog, the default name is the current document name. You can quickly change this to match any existing file.
1. Make the list of files the active element.
2. Click on a grayed-out filename, which momentarily turns black.
3. The Save As field now contains the filename you just clicked.
You can modify the name (adding, say, "version 3") or overwrite that existing file you clicked.
