in your normal view of your todos press "n" for new item.
when that is open, you right click on the task line and choose "add keyword for this search".
you then give the bookmark a sane keyword. I like "gtd" as keyword since you can type that easily with left hand only on a qwerty keyboard. save the bookmark someplace and you are good to go.
now if you type in "gtd " plus any note name in firefox's address bar you instantly add the note to your toodledo list.
it has no other info set tho, but i like that because i use it for quick notetaking, so i dont get distracted while i work and still have a feeling of having captured the todo.
at your next process, you just go to the items with no folder, and they are all there for you to process and decide if they are project or next actions etc. :)
