Page Meta
VoodooPad Pro has a feature that lets you set arbitrary keys and values on a page, which can the be used later on in script plugins or triggers.
To add meta values for a page, bring up the Page and Document Inspector and select the "Page Meta" tab.
Scripts and Triggers
Meta values will be useful for you when combined with triggers or script plugins. Here's an example of a script plugin that uses a meta value named "todo" given to certain pages. It searches through all the pages in a document, finds the ones with the "todo" meta value set, and inserts those names in the current page.
