FlowSheet DIFF quick-start

FlowSheet DIFF takes two spreadsheets--the "base" and the "update"--and compares/contrasts them. There are four windows involved

1. The FlowSheet for the "update" spreadsheet
2. The FlowSheet for the "base" spreadsheet
3. The Value-diff window, on which circles and stars show the cell-by-cell numerical differences (update-base).
4. The Control Panel window, which lets you choose how to display the flowlines in the other three windows, and what to display in the panels below.

There are a few extra symbols:

• The size of a circle represents the magnitude of a postive number; the size of a star represents the magnitude of a negative number.
• A red "X" shows where a formula is different between the two sheets.
• The Control Panel can list all of the cells with different formulae.

The multiple sheets interact as simply as possible:

• Clicking on a cell on any grid "opens" or closes the cells on all grids together.
• Scrolling any one grid scrolls all the grids together.
• You can choose to list all the cell-by-cell formula differences (instead of displaying a cell's disentangled formula)
• Pressing the space-bar cycles between the three grids, bringing each to the front... so, for example, you can superimpose large grids and see each in turn.
