Entering or Modifying Relationships by Editing Marks
Relationships are formed by putting a mark in the intersection of a row and a column. A mark for a row in a column means that the column is a prerequisite for the row. (See reading the matrix).
The user may enter relationships by one of two methods:
Marks may be directly by selecting a intersection square between a row and column and pressing a number between ZERO (high) and NINE (low) and the mark is automatically inserted. Pressing a number over an existing mark cause the old mark to be replaced with a new one.
Values range from ZERO (high) and NINE (low). These values represent the strength (or lack there-of) of the relationship between the row and column. Marks can be adjusted in value up or down via direct entry or by using the menu above. Marks can be made visible or hidden individually, or en-masse via the menu items below.
PSM allows users to change the default representation of marks (The numbers 0-9 color coded) to whatever color or cell value desired. PSM comes with several different set schemes as examples. Regardless of the set used PSM takes its input as 0-9. For more information please see the properties topic.
The mark menu below is obtained via the right mouse menu or from the tools menu (as shown).
You may add notes to any mark by pressing Control+A (^N) or selecting Note...
from the menu above.
You may use Control+A (^A) to select all of the text of a note. You can remove a note by emptying the text or by pressing the delete button.
Notice: while editing notes, the grid, most menu items and the toolbar are disabled. One the notes window is closed, the features are re-enabled.
