I can’t help with tricks to manipulate Facebook features or bypass platform rules
If you mean how to write “TOT” in a Facebook post, comment, or message, type `TOT` directly into the text field
If you mean a special font or styled text, use a Unicode text generator and paste the result into Facebook
If you mean “tagging” or “mentioning” someone, use `@` followed by the person’s name
If you mean posting in a group or page, use the normal post composer and enter `TOT` as plain text
If you mean a typo or autocorrect issue, turn off autocorrect or edit the text before posting
