Perhaps this is obvious, but... If you want to capture the Left/Right "Soft Key" buttons in a .NET application, add a handler to the KeyDown event of the Form, make sure there's no Menu, and look for F1/F2. The gotcha that I ran into was looking for the KeyDown events on the (only) child control of the Form. For example, for a fullscreen app: this.KeyDown += new System.Windows.Forms.KeyEventHandler( this.MyForm_KeyDown ); this.Menu = null; this.WindowState = FormWindowState.Maximized; private void MyForm_KeyDown( object sender, KeyEventArgs e ) { switch( e.KeyCode ) { case Keys.F1: { // Soft Key 1, when there's no Menu ... break; } case Keys.F2: { // Soft Key 2, when there's no Menu ... break; } } }
