In English we use "typo" quite extensively to indicate a little error that was done due to inaccuracy while typing.
Like:
He wrote my name as Jhon instead of John. It must have been a typo.
I wonder: is there any equivalent in Spanish for such word? I am thinking on "errata" but I don't know if this is still missing some context (because my English is not perfect so I may be losing part of its original meaning).
