In 2015 I realised there was a direct correlation between the time of night, and the prevalence of these error messages in Vim:
"E492: Not an editor command: Wq"
This also extends to its FreeBSD cousin nvi:
The WQ command is unknown.
Maybe I should just map all these mistypings to
wq and be done with it. But then I feel like this key combination has won. So I’m going to continue mistyping it, in some vain attempt to
maintain salvage my pride.
