Re: [Dynapi-Dev] Keyboard events in HTMLTextBox

[Raymond I. <xw...@ya...>]

Hi Stephen,

I've seen your post sometime and I believe the way you
did it was to use a Java Applet to capture the keys?

I believe Kevin is the best person to port such
function in DynKeyEvent since he had done an excellent
job with DynKey and TabManager.

PS. I think such extended keybard fnuctions should not
be enabled by default.
