Important Word List

Tools - Important Words ...
Open the List of Important Words where you can add or delete words (in plain text). The List is used by the Important Word Rule, a standard rule .
Gravity will flag incoming articles containing these words as Important (a red exclamation mark). You can then filter the display to quickly show articles that are important or use the important status in rule or filter conditions.

= Marked as important

Advanced Notes:
The Important Word Rule is a Standard Rule and can be edited, although most users use the default actions. For example, you could edit the rule to add a positive score, add these articles to the watch list, email them to someone or yourself, etc.
You can leave the Important Word Rule alone and create a second rule that uses "Articles marked as important" as a rule condition. A rule like this should be placed after the Important Word rule in the rule list.
