Launch charmap.exe to see what the codes are for your
accented letters, then do this in order to write Élève:
Numlock on
Hold down the Alt key
Type 0201 on the numeric key pad
Release the Alt key
Type L
Hold down the Alt key
Type 0232 on the numeric key pad
Release the Alt key
Type ve
As you see from the responses, there are several different ways to do
this. Personally I like a small free application called Allchars http://allchars.zwolnet.com/introduction.html
It runs in the system tray and works with all Windows programs. To use
an accent or special character, you first press and release Control (you
can change this to another key if you prefer) then two keys which
together make up your character. For example, typing a comma plus c
makes ç, ' plus e makes é, ^ plus o makes ô. and so on.
I have used it for many years and can recommend it.
