Yes, this key is a mystery.
FWIW the ` key is used by Word in a programming context, for want of a
better expression - it's used by some database driver/provider versions
to quote stuff such as table names in SQL SELECT statements, e.g. if you
insert an Excel .xls worksheet using a DATABASE field, or record a
MailMerge OpenDataSource.
I don't know about the US keyboard, but the UK version typically has
three characters on it:
a. at the top is a ¬ (Unicode 0x00AC NOT SIGN) which you do get when
you shift.
b. at the bottom left is a ` (Unicode 0x0060 GRAVE ACCENT) which the
unshifted key gives you
c. at the bottom right is a character that looks like | (Unicode
0x007C VERTICAL LINE ). The only key combination that seems to get you
this is Alt-Gr+the key, but what is inserted is actually ¦ (Unicode
0x00A6 BROKEN BAR).
On the UK keyboard there is usually a key to the left of the Z key with
a backsash \ at the bottom and a ¦ (Unicode 0x00A6 BROKEN BAR) but
shift+this key actually gives you | (Unicode 0x007C VERTICAL LINE ).
Confusing when at least one of these is used for the Unix "Pipe"
character. (
