I am using Winforms.
I have added the extended Clear button to my layout.  When pressing, I just see a lower case 'a' appear in the focused entry box.  No clear or deletion of text happens.

I see in the Keyboard Layout Creator that the Clear button contains the 'a' key with Control lock enabled and the Delete key.  But looking in the output xml, I do not see any indication of the ctrl lock option being set.  Is there something I am missing that enables the Ctrl+A feature to work properly?

Thanks that worked for me!
