Where are punctuation marks on a keyboard?

Answer 1

Most of them are down in the lower right corner. The comma, period, slash and question mark are there, with the colon, semicolon and quotes; the exclamation point is at the upper left, generally shift-1.
Other special characters are across the shifted numbers.

Answer 2

Punctuation marks are typically located on the top row of the keyboard above the letters. Common punctuation marks include: period (.), comma (,), apostrophe ('), exclamation mark (!), question mark (?), semicolon (;), and colon (:). They can vary slightly in placement depending on the keyboard layout.
