There are cases in which you would need the Enter key to operate as the Tab key. In order for the Enter key to be used as a Tab key, you could use code similar to the following:
private void Text1_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == 13) //Determine Enter { SendKeys.Send("{TAB}"); //???Fake??? Tab press e.Handled = true; } }
