[quote="Kepler's laws of planetary motion"]
1. The orbit of a planet is an ellipse with the Sun at one of the two foci.
2. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.
3. The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit.

[quote="The Three Laws of Robotics"]
- The First Law: A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- The Second Law: A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
- The Third Law: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Link and Anchor
The HTML anchor can be used in Discourse as easily as in a typical HTML document. Anchors assist when linking to a specific section of an article. Structurally, anchors are like a HTML link <a>, but with a name attribute instead of href – which makes it a link target.
Link and Anchor (code)
<a href="#ankhor-morpork">Goto anchor</a>
<a name="ankhor-morpork"></a>
Features and Usability
Image Grid
I found Introducing image grids in posts which prompted me to add an example to Discourse Tips and Tricks.
Add (a minimum of two) image links between [grid]...[/grid] tags for an Image Grid. Grids will display in two columns on mobile; and three columns on desktop devices. *Richt-click to open an original image in a new tab.
Image Grid template:
[grid]
[/grid]
DiscoTOC (Table of Contents)
DiscoTOC is an automatic TOC generated via a button in the Composer gear menu.
This Discourse theme-component allows automatic TOC to be generated from the markdown Headings of the initial post in any given thread. This is especially beneficial for the creation of Tutorials and similar posts.
Update:- DiscoTOC is activated for T2 and above.
Forum Keyboard Shortcuts
At the bottom of the Site menu is a button that launches a modal window listing keyboard shortcuts available for use on the Manjaro forum.
Due to an unfortunate design condition, this button is obfuscated when all disclosure dropdowns are expanded, and can be easily overlooked.
Shift+? will quickly access the global Keyboard Shortcuts window.

Discourse Spoiler-Alert
I attempted to create a spoiler such as typically used in many forums;
[spoiler]I'm feeling spoiled[/spoiler]. It didn’t work.
Here's why:
It turns out that Discourse Spoiler-Alert is an official Discourse plugin that, when activated, is available from the Composer 
menu.
I suppose that a Disclosure element already provides this basic fuctionality; and is more common due to HTML5 adoption. Plus, it doesn’t require an additional plugin.
Is it worth having a spoiler type disclosure purely for old time’s sake?
