this

The designator this describes the current note (i.e.the note currently in focus). The focus of this can vary slightly by context:

• in $Rule & $Edict: the note whose rule is running
• in $OnAdd/OnRemove: the note that is being added/removed. In context, an attribute with no designator thus refers to the note running the action
• in $AgentQuery: the note that is being examined
• in $AgentAction: the alias that is being examined
• in find(), collect(), etc.: the note that is being examined

Beware of nesting changing the context. Consider the following rule:

$Text=find($MyString==$Name(this)) 

Although the overall context is a rule, the rule contains a find, which in turn holds the 'this' designator. Therefore in the above example 'this' is evaluated in the context of the nested find() and not as in a simple $Rule. The problem is resolved by using a different designator: see 'that'.
