Yes, it is definitely possible, and even fairly common. There are many plugins that modify stored tiddler content (or rename tiddlers, or even *delete* tiddlers), without any user-initiated editing activity. For example: http://www.TiddlyTools.com/#QuickNotePlugin http://www.TiddlyTools.com/#CommentPlugin http://www.TiddlyTools.com/#DiscussionPlugin http://www.TiddlyTools.com/#PasteUpPlugin http://www.TiddlyTools.com/#ListboxPlugin http://www.TiddlyTools.com/#TaskTimerPlugin http://www.TiddlyTools.com/#PanelManagerPlugin and many, many more... So, it would seem that your proposed technique of tracking the start/ end offsets of the relevant tiddler content won't be reliable, unless you can also ensure that no other tiddler-modifying plugins are installed in the same document (or at least, make sure their functionality is never triggered while your interface is being used). -e Eric Shulman TiddlyTools / ELS Design Studios ---- TiddlyTools needs YOUR financial support...
