If your "global variable" is only needed when *viewing* tiddlers in the
Story River, or when *previewing* while editing a tiddler, but *not* in the
Sidebar, SiteTitle, etc., you can do this:
1) In $:/hb/HighlightIntensityKW, instead of just containing the value
(e.g., "12345"), use \define, like this:
\define hb-highlight-intensity-kw() 12345
2) Tag $:/hb/HighlightIntensityKW with "$:/tags/Macro/View"
Then, you can use <<hb-highlight-intensity-kw>> in tiddler content or as a
widget parameter value and it will be replaced by 12345 as before, but
without causing the entire PageTemplate to be re-rendered. Thus, the Story
River's current scroll position will not be lost.
