Foreign language accent marks can be applied to words in a Windows Word document in different ways.

One such way is to employ ALT codes. For example, to insert a lower-case á, key ALT+0225. For an Ñ, key ALT+0209.
Note: the numeric keypad, rather than the number keys at the top of one’s keyboard should be used.

The tables below provide the most commonly used ALT codes for Spanish accent marks.
