Template:M-

This template is used to easily make the em dash (—) character, not supported by most keyboards.

The — is used to indicate an abrupt change of thought or an interruption in the linear flow of a sentence. It is frequently used in lists to separate a short 'prefix' from additional information, or to indicate an open range of dates. The em dash is twice as wide as a hyphen/minus sign.

Example:

• The Beast Wars cartoon series—called "Beasties" in many overseas markets.
  

It is possible to permanently convert the {{m-}} template into a — sign by typing {{subst:m-}} ...but it's probably easier just to copy the character out of this template.
