With the Num Lock Key, hold down the Alt key and type the following numbers on the keypad - it will not work unless you use the keypad:
E Acute - 130
E Grave - 138
A Circumflex - 131
A umlaut - 132
C Sidila - 135
There are many others in the number range 001 to 250 or so, I suggest experimenting or looking in the back of an old MS DOS book
