Webin has released ReadKit 2.4, a major update to the RSS client and read-later app with improvements to keyboard navigation and the introduction of a new sharing service. With version 2.4, most keyboard shortcuts can be customized under the Shortcuts tab of Preferences (this Webin blog post offers an explanation of the new shortcuts). ReadKit also adds support for the Buffer sharing service, which enables you to share links to your social media connections immediately or schedule them to appear throughout the day or week. The update also adds the capability to highlight code blocks, brings more granular preference settings on a per-account basis, adds a customizable sharing toolbar, improves sync speed of the built-in RSS engine, and improves compatibility with OS X 10.9 Mavericks. Unfortunately, ReadKit 2.4 drops support for 10.7 Lion. ($6.99 new from the Mac App Store, free update, 4.0 MB)
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.
