Windows CTRL + SHIFT + L

[Shellworth 0]

So I accidentally keyed CTRL + SHIFT + L  while working in the body of a note. A slightly gray box in smaller Monaco font appeared, (see below) and this carried over to my mobile device.  What is this feature and where can I learn more about it?

That's the shortcut for code block styling. Basically is takes what everyou had selected and displays it in a gray box using a monospaced typeface, and no other styling (no colors, boldface, italics, etc.), though you can apply those afterwards.

The tool on the editing toolbar is to the right of the highlighter tool, and to the left of the bulleted/numbered list tools. Hover over tools on the editng toolbar to see what shortcuts are associated with the tool. You cana also find formatting shortcuts from the main menu: Format / Style
