I guess that depends on your operating system and keyboard layout. For example, on a French keyboard you generally have a key for it. On a standard German "dead-keys" keyboard, you'd use the key sequence [´] [e]. On any Unix/Linux keyboard with Compose key, use [Compose] [´] [e]. If you have a way to enter Unicode characters directly by code number, the character is U+00E9 (decimal code 233; probably on Windows you could enter it by holding Alt and typing on the numeric keypad [0] [2] [3] [3], but I can't check because I don't have any Windows). When all else fails, you can go to the character table, seek for that character, and then copy/paste it.
