This, initial step, is where you dump everything that you need to do. If you have been using the Integrated Thinking Environment for a while already you may already have a good start on this. Even so, if you want to switch to the GTD method spend some time here to make certain that you get all your action items noted down.
This is not where you Clarify, Organise or Review, just get your notes, from your brain, from all your lists, from all your notebooks into one centralised place.
Add new Action Items by clicking on the + at the bottom of the table. If the list becomes too long, click on the Checkbox to remove the items from the GTD Action Dump view.
