TNM Map Bindings
Binding Description
%% Replaced with a single percent.
%A  Replaced with the event arguments.
%B Replaced with the handle for the binding that matched the event tag.
%E  Replaced with the unique handle for the event.
%I Replaced with the handle for the item or an empty string if the event is generated for a map.
%M Replaced with the handle for the map.
%N Replaced with the event name that triggered the binding.
%P Replaced with the pattern that matched the event tag.

Events can trigger event bindings, which allow executing arbitrary Tcl commands. Event bindings are either associated with an item or with a complete map.

A binding is defined by a pattern, which is matched against event tags. The match uses the same rules as described for the Tcl string match command. 

The body of an event binding is a Tcl script, which is executed in global context whenever an event tag matches the binding pattern.

Events that are associated with a map item will first trigger all event bindings for that particular item. Afterwards, the event will be passed to the parent item (if any). 

Once the event has reached the root item, the event will be passed to the network map. Events that are associated with a network map will only trigger the event bindings defined for that particular map.

The processing of event bindings can be controlled by returning a break or continue return code from the script. 

A break return code will stop event processing. 

A continue return code will stop event processing for the current item and immediately start with the bindings defined for the parent item (if any) or for the whole map.

Event details can be accessed in the script, which is bound to an event by means of % substitutions. These substitutions happen before the script is passed to the Tcl interpreter.
