Quicksilver is a great Mac app for smartly launching any application based on your preferences. In short: less clicks, more action. It can even do web searches. Now you can include killer GTD functionality with
Quicksilver via Actiontastic integration.
One of the most basic tenets of GTD is brain dumping; getting all those projects and thoughts out of your head and into a trusted system so you spend less energy worrying about them, and more energy doing things that are actually productive. Having to switch away from the application I’m currently using in order to create a new item in my inbox totally trashes my train of thought, and being able to simple hit a hot-key to brain dump makes it easier to keep up with the GTD methodology. Actiontastic includes Quicksilver functionality as a QS action bundled with the app, which is much more elegant than the unfortunately clumsy Quicksilver Action Kinkless GTD uses to accomplish the same thing.
