There is no way of firing a browser event manually. There will however be 
a way of firing all the actions bound by a given kss rule, on a given 
node (which ends up at the same result).

Currently the following methods can be used. They are both methods on an 
_event binder_ instance in javascript.

  binderinstance.__continueEvent__(eventname, node, defaultParameters)

This executes the actions bound on the binder instance, for the given 
eventname, on the given node.

  binderinstance.__continueEvent_allNodes__(eventname, defaultParameters)

This executes the actions bound on the binder instance, for the given 
eventname, on all the nodes bound in this instance.

These were made to cover use cases for continuation events. There are 
examples in kss.demo for this as well as in the upcoming 
kss.plugin.livesearch plugin. There are also some comments to explain the 
call signature of these methods in the eventreg.js file.

There is currently no commodity method for calling up all the events on 
all the necessary binder instances (or on the singleton binder instance 
as in case of click), on a given node - this is what you would like to 
have. We will take care of providing a clean API for this task in the 
next version of kss.

I cannot go into deeper explanation here about what an event binder 
instance is or how you would look it up from the registry. I will, 
however, try to write a small recipee page on kssproject.org about this, 
which will enable you to use this even before the cleaner API arrives. No 
deadline promised though.:(

Best wishes,
