System 7.5.5 Update -- It's clear now that Apple has not yet released System 7.5.4, and in fact, according to sources, is fixing problems relating to the IR capabilities of some Macs. The update, when it comes out, will be renumbered to 7.5.5. The next mention of it in TidBITS will be when it's actually available. [ACE]
Adding Links in Snow Leopard's Mail
Apple Mail in Snow Leopard now has a Command-key shortcut for adding a link to an email.
If you use plain-text email, this will not be helpful at all, but if you send styled email, it's a nice shortcut for adding URLs to your email messages. Simply select the word(s) you want to make into a link, press Command-K, and enter the URL to build into the link.
