Question

Basically in a C# Windows Form Application I am working on I have 2 buttons I press button1 and button2.

How do I make it when I press 2 custom keys simultaneously(eg. CTRL+L) the program does the steps coded for button1? Keeping in mind that the window might not be active.

I have looked at this: Keypress To Simulate A Button Click in C# but I don’t think this would work if the window isn’t active, and its also only one button pressed not two.

In Form KeyUp Event and the Properties is KeyPressPreview = true you can achieve this task.

   private void Form_KeyUp(object sender, KeyEventArgs e)
   {
       if (e.KeyCode == Keys.L && e.Control)
       {
                yourButton.PerformClick();
                e.Handled = true;
        }
    }

or

if you want in Keypress Event

private void Form_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.Control && e.KeyCode == Keys.L)
    {
            yourButton.PerformClick();
            e.Handled = true;
    }
}

EDIT:

I realized that the OP want to the keypress Event from his statement “but I don’t think this would work if the window isn’t active”
