Can I use CTRL-R and CTRL-H shortcuts in an Internet Explorer plug-in?

I am working at an Internet Explorer plug-in. (afp viewer plug-in)
I want to use the shortcut keys CTRL-R and CTRL-H to do some actions (reset view,...).
The problem is these keys are shortcuts for IE.
Is there a way to get the keyboard messages before they go to IE?
Or should I use other shorcuts?
