I installed it just now to see what it was. Neat!
Anyway, looks like you need to open the VBE and put the cursor in a place where you would like to insert code. Then in the VBE, go the Tools menu and select "Mark position for recording."
Then you can go back into Excel and select "Record at Mark" instead of plain old record. When you finish recording, the code is inserted into macro at the point you selected.
