What you saw was the act of the the ~ key, which changes case in vi.
Now a lot of the extra keys have escape sequences ending in a ~ (eg ^[[14~
is F4 on some terminals).  Now, if vi doesn't recognise these extended
sequences as referring to a single key press, then it might treat it as
the commands ESCAPE followed by [1 (probably won't do anything) followed
by 4~  - ie it will change the case of the next 4 characters.

So if the OP saw "ROOT" (rather than "R00T") then this is a possibility for
what happened.
