The rule for them is called a hyphenated modifier, as it adds more detail to a noun then one adjective. An example of this is, "He gave me that don't-even-think-about-it look," that gives more information and detail than, "He gave me an angry look."
Dashes are used to extend a sentence and add additional information.
The black dots and dashes between states on a map represents the state boundaries. The dots and dashes are used to outline the state.
Dashes can be used to indicate a stronger break in a sentence compared to commas. They are often used to set off information that is somewhat abrupt or surprising, or to emphasize a point. Dashes can also be used to create a more informal or conversational tone in writing.
Yes; there are none.
Actually Morse's original code used dots, dashes, long dashes, and very long dashes. It also used 5 different lengths of gaps. This was greatly simplified by the adoption of the International Morse Code (largely developed in Germany then modified a bit by international agreements) to just dots and dashes. The number of different length gaps was also reduced to only 3.
Because hyphens are dashes. Word changes double dashes into em dashes (the long dashes) automatically if there is a space before and after the double dash.
A dash is a punctuation mark that is used to indicate a pause or break in a sentence. There are two main types of dashes: the em dash (—) and the en dash (–). Em dashes are longer and are used to set off a phrase for emphasis or clarity, while en dashes are shorter and are typically used to show ranges or connections between numbers or words.
yes, dashes is a word. (eg. the masked swordsman dashes out from behind the tower)

Dashes should be used instead of commas or parentheses when the additional information is more significant or interruptive in nature. Dashes draw attention to the information and create a stronger break in the sentence, while commas and parentheses are typically used for less interruptive or more supplementary information.
You can use ellipsis (...) or em dashes (—) to mark interruptions in writing or dialogue to show a pause or break in thought. Both punctuation marks are commonly used to indicate an unfinished or interrupted sentence.
