Hey Zeb This event is as usual as like Button_Click event. Make sure you have set the KeyPreview property to true in your Form

thx Amit, But can u give me any example to create Event?

Use Modifiers instead if(e.KeyCode==Keys.A && e.Modifiers== Keys.Control) { ... } Also generate an event for key down instead of override

Answers

putting data with A+ctri key.
