What group of keys do you use to add punctuation marks ON a document?

You're asking about the keys used for punctuation marks on a keyboard. There isn't a specific "group" of keys, but rather individual keys dedicated to each punctuation mark. Here are some examples:

* Period (.): The period key is usually located to the right of the "L" key.

* Comma (,): The comma key is usually located to the left of the period key.

* Question Mark (?): The question mark key is usually located to the left of the semicolon key.

* Exclamation Point (!): The exclamation point key is usually located to the left of the number 1 key.

* Semicolon (;): The semicolon key is usually located to the right of the "L" key, above the period.

* Colon (:): The colon key is usually located above the semicolon key.

* Quotation Marks (" "): Quotation marks are usually entered by pressing the shift key and the number 2 key for double quotes, or the shift key and the single quote key for single quotes.

Keep in mind, the placement of these keys may slightly vary across different keyboard layouts.
