Create "Global" Hotkey for entering tasks while working in other programs
While doing a task in another program, i'd like a way create tasks in Get it Done. Currently, I have to open the website, move to my iPad/iPhone etc to enter the task. I'd like to hit some key combination, have the edit task entry screen appear (similar to hitting "+" or "=" in the web application), enter my data, save and move on. The purpose of this is to be able to capture items when they shoot into my mind.
My music player has a feature where I can assign "global" hot keys so I can start and stop music etc while in any screen, in any program
OmniFocus has this and describes it this way: Capture it all on the fly with the quick entry panel, accessible via keyboard shortcut from virtually any application.

One strong principle of the GTD method is throwing tasks into your Inbox as you think of them and organizing them later. This is restricted if you first have to open the app, go to the Inbox and click on the Add button. We need a user-configurable key combination like Ctrl-Alt-N to open a gadget/widget/whatever on the desktop to receive the task idea, then go away when we hit Esc.
