Does it happen to teach Tiddlywiki to others (e.g your students)? All the time they have to edit the tiddler to see what is the underlaying script/content to produce such rendered content.
I use a small view template like this
<$list filter="[all[current]!is[system]]">
<details>
<summary>Code</summary>
<$codeblock code={{!!text}} language=xml/>
</details>
</$list>

To give a try download (viewtemplate_reveal-tiddler-code.json (338 Bytes)
) and drag and drop into https://tiddlywiki.com/prerelease

Further notes:
If you have Utility 3.2.3 — utility kit for authors and developers installed then it automatically shows
- the content of all tiddlers tagged
$:/tags/Macro
- the content of all tiddlers tagged
$:/tags/ViewTemplate
You can manually tag a tiddler with show-content to see its contents while in view mode
You can manually show raw content using filter in Sidebar > More > Utility Tab
This is how tiddlywiki.com should work. <rant>However, the way that TW documentation tiddlers are constructed from nested macros does not aid beginners at all.</rant>
