A footnote or endnote is usually indicated by a superscript number immediately following the text or phrase to which the note refers. Some requirements demand other symbols instead of numbers if there are a few footnotes in the document. For example, asterisks (*) or daggers(†) are used instead.

Footnotes are short notes at the bottom of the page that provide explanations, additional comments, or an understanding of a particular word or phrase in the document content. Endnotes are the same as footnotes but appear at the end of an entire section or document.

A vector is a mathematical object characterized by magnitude and direction. To define a vector, you can use:

• a bar above () - see how to work with Superimposing characters,
• an arrow above (),
• bold or gothic font () - see how to insert Double strike or Blackboard bold symbols and gothic symbols in Word,
• a letter with a tilde (~) underneath it () or (), see below how to create such vectors.

Ordinals (also known as ordinal numerals or ordinal number words) represent the position in a series. They describe the numerical position of an object, e.g., first, second, third, etc. By default, Word converts ordinal numbers to superscripts:

Often you need to insert several words or letters from a language with accents like French or German. For example, to type a foreign company or person name.

There are two types of dashes in Word documents: the en dash (–) and the em dash (—). The em dash (—) is typically about as wide as a capital M. The en dash (–) is about as wide as a capital N. There are different rules and standards for how and when dashes may or may not have spaces around them.

A per mille sign ‰ (also mentioned as per mil, per mill, permil, permill, or permille) represents thousandths, 1/10 percent, or the number of thousandths of something in total.

An angle ∠ is a geometric figure formed by two rays - sides of the angle, emanating from the point called the vertex of the angle or angular point.

The inverted question mark ¿, and inverted exclamation mark ¡, are punctuation marks that start, respectively, interrogative and exclamation sentences (or clauses) in writing in some languages, such as Spanish (called as signos de interrogacion and signos de exclamacion).

Angle brackets ⟨ ⟩, also known as pointy brackets, triangular brackets, diamond brackets, tuples, chevrons, guillemets, broken brackets, brokets, (often substituted informally by less-than < and greater-than signs >) are used in different areas, for example:
