WPF Form Toolbar Short cut keys in Outlook 2003 VSTO addin

Question

Hi,

I am working on a outlook 2003 addin(using VSTO), which launches a wpf window. I have added menus and tool bar on this form and assigned shortcut keys for them.The problem is that these shortcut keys are intercepted by the outlook resulting outlook default action.

Example: Alt+f invokes file menu on outlook, instead of menu in wpf window.

I found some links pointing to Addin Express. Is there a way to get the work done in VSTO AddIn.
