There's a variant of the US layout called altgr-intl where instead of making ' a dead key you can do RightAlt-e for é.

Is that literally the same character for both? On my layout `e leads to è whereas alt-gr+e = é. é != è in many languages.

janus24 specified "é (' + e)". That's neither ` nor è.

Not all languages that use é have a use for è.
