Numbers must be typed in on the number pad of the keyboard.
It also works here! €
UPDATE: 11 Dec 2010
I have just discovered the above is an old way of inserting symbols and is not unicode.
To be able to add unicode symbols easily for Windows XP SP3:
- In the registry key HKEY_CURRENT_USER\Control Panel\Input Method
Look for a value named EnableHexNumpad
If the value does not exist create a String value with that name.
- Set the value of EnableHexNumpad to 1.
- Reboot the PC.
- Now in OpenOffice, to get the Euro symbol, hold down Alt, press + on the numpad, followed by the hexcode for Euro, then release the Alt.
Alt + 20ac. It works here too €
Alt + e3f.
