Slightly off-topic, but this did came up...
Can someone manage to type
\\ in a comment?
Yes, we can! Until recently, Arturo's advice to type
`\\ ` was the only decent workaround, but a few weeks ago, double backticks have been enabled in comments. Thus, in a comment you can type
``\\`` to obtain
\\. For more details have a look here: How do I mark inline code?
