.NET Magic TabControl Help

I'm creating new tab pages programmatically, and each page has a richtextbox as it’s only control. My question is: how do I access the members of my richtextbox from the mainmenu of my mainform.

For example, if I were to simply put the rtb on my mainform, I could call rtb.Paste(), or rtb.Copy() etc… But this does not appear to be the case while on a tabPage.

The project I’m working on is a simple tabbed text editor written in c# which can be found at http://sourceforge.net/projects/sharpedit. I am very new to C#, and I have been fussing with this problem for a loooooong time. If anyone could take the time to check out my code & help me figure out what’s going on, I would be incredibly grateful

Thanks
