Semicolon ; (I've always thought of the semicolon as an "and")
In addition to using a semicolon to join related independent clauses in compound sentences, you can use a semicolon to separate items in a series if the elements of the series already include commas.

Dash -- (i use this one as "hey i'm interjecting my own thought here - take it or leave it") 🙂
Use a dash (represented on a typewriter, a computer with no dashes in the type font, or in a handwritten document by a pair of hyphens with no spaces) . . .
for example:
* to emphasize a point or to set off an explanatory comment; but don't overuse dashes, or they will lose their impact.

The boys--Jim, John, and Jeff--left the party early.
As you can see, dashes function in some ways like parentheses (used in pairs to set off a comment within a larger sentence) and in some ways like colons (used to introduce material illustrating or emphasizing the immediately preceding statement). But comments set off with a pair of dashes appear less subordinate to the main sentence than do comments in parentheses. And material introduced after a single dash may be more emphatic and may serve a greater variety of rhetorical purposes than material introduced with a colon.
