Windows Form - Override Enter with an other key

Question

Is there a way in Windows Form to activate the currently focused button/control with the Q key? Or override the Enter, so that pressing Q activates the currently focused control like Enter does? I want the user to be able to control the application with just the left hand on Tab and Q to cycle controls and activate them.

private void Form2_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Q)
            {
                e.Handled = true;
            }

I already have this, but what do I need after the e.Handled to activate the current focus?

To move focus to different controls, Tab is enough. Do you mean you want to use Q instead of Enter on a Button? What about a TextBox? — Reza Aghaei
The thing is, everything is automated you just have to make some decisions and press one of the buttons i have and it would be nice if the user could use the right hand for mouse control and the left one for Tab + Q to select a button and activate it, without using enter. — Drake

As an option you can override ProcessCmdKey and check if the key is Q then send Enter using SendKeys.Send and return true to indicate you that you processed the key:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    if (keyData == Keys.Q)
    {
        SendKeys.Send("{Enter}");
        return true;
    }
    return base.ProcessCmdKey(ref msg, keyData);
}

You can limit the behavior to buttons by checking this.ActiveControl is Button if you need.
