Sometimes they capitalize the first letter within the bounding asterisks, sometimes they do not. Sometimes the verbs in the asterisks are third person singular and have -s or -es after them, and sometimes they do not.

Do you put the * Before or after?

For editing and footnote purposes, the asterisk will appear before a word that needs correcting or a sentence that needs elaborating, and the additional information will be placed beside a corresponding asterisk at the bottom of the page.

What do you use after an asterisk?

A dagger, obelisk, or obelus † is a typographical mark that usually indicates a footnote if an asterisk has already been used. The symbol is also used to indicate death or extinction.
