By accident, I noticed something "markdown-like" on the Mac version. As someone who takes lots of code chunk notes, I find myself often
creating a one-cell table
pasting the code from editor or command line
formatting it mono-space font
This sets the code apart from the rest of the explanatory text.
Today I was doing this for a markdown sample and I stumbled on the fact that if I start a line with three back-ticks and press enter, it automatically turns into a mono-space font box. This works for me on Mac OS with EN 6.5.
