The RefreshMechanism allows the refresh cycle to be throttled (or deferred) when rapid changes occur to the same tiddler. It is used to maintain responsiveness while editing a draft tiddler, but can also be used on other tiddlers.
The rules governing refresh throttling are:
* When a change notification occurs, throttling will only take place if all of the modified tiddlers meet at least one of these criteria:
* If the refresh cycle is to be throttled, a timer is set for the internal specified in [[$:/config/Drafts/TypingTimeout|Hidden Setting: Typing Refresh Delay]] (cancelling any preciously set timer)
** When the timer fires, the refresh cycle is triggered, passing the aggregated titles of all the deferred refresh cycles
