Emacs quoted insert

Good morning folks out there,

I’ve got another neat little feature of emacs for you today, it’s called quoted insert.
I stumbled on this, because I use spaces for code indentation in my emacs, but I needed to insert an actual TAB character.
So, in this situation, the combination C-q <TAB> is the way to go, which interprets the next typed character in a quoted fashion.
