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)
Open a Finder Window with the App Switcher
If you don't have any Finder windows open and want to switch to the Finder and open a window in one fell swoop, bring up the app switcher with Command-Tab and tab over to the Finder icon. While still holding down Command, press the Option key, and then release the Command key. You're switched to the Finder, with a new default window open for you.
