Keypresses Like F1, F2 etc.
My application is MDI and each child window has a memo on it.
When you press keys, it appears in the memo as you would expect as the memo has focus. However, I still want the parent form to respond to things like the function keys and Ctrl-key combinations.
Is there a good, bad or easy way to do this?

You can use Virtual Keys
make a search in delphi help about Virtual Keys & you'll find a good example.
if you didn't I'll send you an easy code.

I just came back to delete this question as I'd found what I was looking for. Virtual keys didn't really help a lot actually and I did it in the end by pinching info out of two separate code examples:
If (key=71) and (shift = [ssCtrl]) Then
Begin
// Ctrl-G Goto Line Number
End;
Thanks anyway!

Application for question to be deleted made with mods.
Suggestion made unfortunately did not solve the problem. (Virtual Keys can be used to detect the Control key but apparently not with another key such as Ctrl-G).

At risk of being ignored ;-) why don't you use the FormKeyDown (or component version of KeyDown) and send that to the parent form?
procedure TForm1.FormKeyDown(Sender:
begin
Form2.FormKeyDown(Sender, Key, Shift);
end;
That captures virtually every keypress with the exceptions of PrtScr and one or two others.

That's what my code (posted above) does... :)
It uses both the shift and key values - rather than Virtual Keys.

You could use keyboard event.
Example:
keybd_event(vk_return,0,0,
If you want to do two keys:
keybd_event(vk_control,0,0
keybd_event(vk_escape,0,0,

TDK_Man - I've read through all your posts and I cannot find any which mention FormKeyDown...!

Sorry - you misunderstood what I meant.
When I said "That's what my code (posted above) does", I was refering to the use of 'key' and 'shift' rather than Virtual Keys:
If (key=71) and (shift = [ssCtrl]) Then
Begin
// Ctrl-G Goto Line Number
End;
... which is in my memo's KeyDown section.

The only thing I don't seem to be able to detect is Ctrl combinations like Ctrl-G so I can pop up a panel for a Goto line number feature.
