Adding a select all shortcut (Ctrl + A) to a .net listview?

Question

Like the subject says I have a listview, and I wanted to add the Ctrl + A select all shortcut to it. My first problem is that I can\'t figure out how

Answer 1

private void listView1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyData == (Keys.A | Keys.Control))
        foreach (ListViewItem item in listView1.Items)
            item.Selected = true;
}

To only do it on Ctrl+A, not on other combinations like Ctrl+Shift+A etc.
