Text box + ctrl Shortcuts

Question

So I've got this form with a bunch of text boxes. I had to modify one from what Visual Studio makes the 'default' settings. The only thing (that i can think of) that I changed was: 1. I added a context menu 2. I made it multi-line But now none of my ctrl shortcuts (ctrl+A for select all, ctrl+C for copy, ctrl+V for paste, etc...) work anymore. So now my questions... First off, how can I get the shortcuts back. I tried various code structures in the 'KeyDown' event for the text box. I can get the ctrl key to fire off code, and I can get the 'A' key to fire code, but I can't get BOTH to do so. So how do I get my ctrl shortcut functionality back??? Secondly, how did it happen in the first place? Did either of my 'customizations' break that functionality? Personally, I can't se how. But that's just me... So any and all help with this issue would be greatly appreciated. Thanks...
