RichKeys, The sign is not an upper case I. The sign is made using a special key. The key is normally located right above the "enter" key.
Do you see it? It's on the same key as the "\", and it should be beneath "backspace". Just hold shift when you press it, and it should give you "|".
Thanks Morran ...I think my keyboard must be very different!
However I found that the key to the left of the "Z" works (eg Shift +\) it shows as a dotted line on the keyboard but produces "|" (apparently its called a "pipe"!
