How to create quick-entry dialog with system-wide shortcut?

Question

I really like how Things gives us ability to capture todos without switching to the app. How to do this? I can't find any relevant code with google. Any ideas, urls or maybe code snippets?

Answer 1

I'm not familiar with Things, but it sounds like you're describing a Service. Services live in the application menu under Services.

TextEdit.app provides a "New Window Using Selection" service, for example.

Answer 2

I learned about global hotkeys from the example on this website here.
