Creating shortcuts key

See here[^].

Create a ToolStripMenuItem to do the job and assign a Shortcut to it. If you don't want a MenuStrip on your Form, put it in a ToolStripContextMenu instead.

Create a Menu for the application and you will find Shortcut key for each menuItem.

Other than that, you can also handle KeyDown event to write your custom logic around each Shortcut key elements. Check EventArgs for KeyDown.

If you are using visual studio, open a form and select a gui control that would react to the shortcut. Click on events and choose the keyDown event. A sample code goes like this.

private void headerGrid_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Control && e.KeyCode == Keys.C)
            {
                // Do something
            }
        }

If you're asking how to implement operations like undo, cut, paste, bold etc. Then, you may choose a richtextbox. It already has default operations with shortcuts but if you want those shortcuts to work even without selecting the control, replace the [// Do something] comment above with richTextBox1.Undo() or something like that.
