I have a grid and I am trapping the OnKeyDown event.

I am trying to detect when the user either hits the Insert key or the letter A or the backslash key.

So in my OnKeyDown evnet I have the code

if Key=VK_Insert then
  Showmessage('Insert key was hit - this works!!!');
if Char(Key)='A' then
  Showmessage('A key was hit - this works!!!');
if Char(Key)='\' then
  Showmessage('Backslash key was hit');

Why does the test for the backslash key fail?

I note that when I hit the backslash then key=220 but Ord('\')=92.  Strange!

I prefer to use OnKeyDown because it is the first event and I can set the Key:=#0 to kill the keystroke and I can test virtual keys.  I can't do this with OnKeyPress.
