In the MDI form, create a menu item for each child form and assign keyboard shortcuts to the items.

The example is right, but the concept being encouraged is not. There should be commands that launch the forms in this case, and how it is called shouldn't be hard coded beyond the minimum. The command class allows for a short cut key to be associated and that should provide the nescessary access. Overriding the keybouard handler is really too low level for what is already provided by the framework.

Hey, This has gone on long enough. What people are trying to tell you is to just assign a function key as a short cut key. These assignments are usually done through the designer but example code is
this.MyMenuItem.ShortcutKeys = System.Windows.Forms.Keys.F1;. Alan. -
Please try out something on your own before posting so many questions. You can assign function keys as shortcut keys for menu items in the form designer. Select the menu item in the designer and look for the Shortcut property in the Property Explorer window.
