To enter an en-dash using AutoCorrect, type at least one character, a space, two hyphens, another space, and at least one more letter, then a space. The two hyphens will be replaced by an en-dash.
— is an em-dash; that is, a dash the width of the letter "m" in the font you are using. It is U+2014. To enter it using AutoCorrect, type at least one character, two hyphens, and at least one more character, then a space. The two hyphens will be replaced by an em-dash.
To insert a non-breaking space (to keep characters together, for example in a telephone number), press Control+Shift+Space on the keyboard.
You can use a non-breaking hyphen in cases where you do not want the hyphen to appear at the end of a line. Examples of non-breaking hyphens are: in a range such as A‑Z or the hyphens in a telephone number, such as 123‑4567. To insert a non-breaking hyphen, press Shift+Control+minus sign.
