hi,
this works ok:
(must also set keypreview to true)

procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
if key = vk_escape then
 begin
  keybd_Event(VK_SHIFT, 0, 0, 0);
  keybd_Event(VK_TAB, 0, 0, 0);
  keybd_Event(VK_TAB, 0, KEYEVENTF_KEYUP, 0);
  keybd_Event(VK_SHIFT, 0, KEYEVENTF_KEYUP, 0);
 End;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
Form1.Keypreview := True;
end;


Regards Barry

This answer ins't exctely what I want. Cause it's too generic and can generate problems with components like dbgrid.
 To make Enter ack like Tab I use this:
 "perform(wm_nextdlgctl,0,0);"
on the onkeydown Event.
I thought that insted of wm_next I could use wm_prior but it did no work.

So, maybe u know a better way to do it.

Thanks anyway Barry

you are wanting to send more than one key at a time so there are not exactly a million ways to do it..tab is ok as we have the wm_nextdlgctl message but
?? wm_prior ,you make this up ?i never heard of before nor find any mention in any pas file or api book.

well there is a vk_prior key

keybd_Event(VK_PRIOR, 0, 0, 0);
keybd_Event(VK_PRIOR,0, KEYEVENTF_KEYUP,0);

Hi VSF

Where you use "perform(wm_nextdlgctl,0,0);" to make Enter act like Tab, catch key 27 or VK_ESCAPE and do "perform(wm_nextdlgctl,1,0);"
That will do the trick. The wParam parameter of perform (sendmessage) is the key.
