Example
Demonstrates how to customize the control's KeyActionMappings collection so that a non-default keystroke can be assigned to perform an application-specific action. This example adds a KeyActionMapping for the F2 key which exits edit mode on an Appointment or Note, saving any changes that were made. It also prompts the user to decide whether they want to remove existing mappings for that key.
