I tried to edit an answer of someone else and got this message:

It's this answer: http://superuser.com/a/112134/151741

I wanted to change

> `Ctrl + Alt + D`

to

> `<kbd><kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>d</kbd></kbd>`

Was the minimum character limit changed sometime? Would this mean that all answers that were created before can't be edited anymore?
