Re: [scintilla] ATL ActiveX Control

Yeah I see your point but unfortunatly there seems little alternative.  Kind of a stupid design on MS's part.  To me it seems like it would just be more intelligent to allow every key to go to the control and let the control descide what to do with it.  Then whatever it doesn't handle let the host of the control descide what to do with it.

Hi Stewart

If it works anything like the C# or VB implementations, you may also
want to cater for the Shift modifier too. I'm really surprised there
isn't a key preview or key event where you can't catch this - it must
be being caught by the ATL container and not raised again or
something!

One other word of warning too - that implementation also takes away
the ability to assign command keys for the arrow keys, al! though I
doubt that is much of a loss as I can't see why you wouldn't want to
use those keys to navigate anyway. Just thought it might be something
worth considering.

Cheers
