Sometimes you want to quickly structure a list of random entries. There are a number of ways of doing it - cut and paste, (shift)/drag and drop, Mark and Throw.
This movie demonstrates the last of these. The idea is that you read through a long list of entries that you've captured and realise there are some themes. You make these themes your entry names and then, in turn, throw matching entries so they become subsidiaries of each theme.
(You can also use Shift and Throw (Ctrl+T) which throws a copy, leaving your original list intact. This isn't in the screencast, but it can be very useful.)
