Creating Extended Characters

The United States-International keyboard layout assigns new functions to the right ALT key (the ALT key on the right side of the keyboard). Use the right ALT key in combination with other keys to create extended characters.

The following table illustrates characters that you can create by using the combination of the right ALT key plus another key, as well as those that you can create by using the right ALT key plus the SHIFT key plus another key:

Creating International Characters

When you press the APOSTROPHE (') key, QUOTATION MARK (") key, ACCENT GRAVE (`) key, TILDE (~) key, ACCENT CIRCUMFLEX key, or CARET (^) key, nothing appears on the screen until you press a second key. If you press one of the letters designated as eligible to receive an accent mark, the accented version of the letter appears. If you press the key of a character that is not eligible to receive an accent mark, two separate characters appear.

In other words, when you use the US-International keyboard layout, Windows automatically accents letters that customarily receive an accent but does not automatically accent letters that do not customarily receive an accent.

The following table illustrates the accented characters that you can create:

Press this key	Then press this key	Resultant character
' (APOSTROPHE)	C	Ç
'(APOSTROPHE)	e, y, u, i, o, a	é, ý, ú, í, ó, á
"(QUOTATION MARK)	e, u, i, o, a	ë, ü, ï, ö, ä
`(ACCENT GRAVE)	e, u, i, o	è, ù, ì, ò
~(TILDE)	o, n	õ, ñ
^(CARET)	e, u, i, o, a	ê, û, î, ô, â
