The Reference Editor display classifies references by section. Codes are presented in a tree structure that, once unfolded, displays the list of attributes. Each reference section is identified by a specific color.
Click on the + (plus) sign to display the contents of that section or reference code.
Click on the – (minus) sign to hide the contents of that section or reference code.
You can then modify the reference type or compatibility directly on the grill by clicking on the desired information. An arrow will appear at the extreme right of the cell to display the list of possible choices.
You can also modify the display colors.
