Press and Hold is the discovery combination that every Windows phone 7 user should know.
We were having a conversation around the Windows Phone 7 on-screen keyboard. In order to keep the keyboard compact Microsoft stows alternate character beneath common keys.

This also works for accented (diacritical) characters.
