describe the scratch grid

 

from the dc forum:

 

This is how I use the scratch pad :

1- I use it for preliminary data gathering.

2- But, mostly, when I want to have an quick idea of "which field is populated with what data", or "what data is populating this particular field", I open the property pane, double click on a field, and the scratchpad automatically updates itself and shows what item contains data pertaining to that field.
