dojox.timing.Sequence.stop
dojo.require("dojox.timing.Sequence");
defined in dojox/timing/Sequence.js
This can only interrupt the sequence not the last function that had been started. If the last function was i.e. a slideshow that is handled inside a function that you have given as one sequence item it cant be stopped, since it is not controlled by this object here. In this case it would be smarter to run the slideshow using a sequence object so you can also stop it using this method.
Usage
