Try to implement global keyboard shortcut in MDI parent/child form and other form by

[scudsong]

I override ProcessCmdKey() in my MDI parent form class and have some keyboard shortcut calling method in same class. But I wish to make these hotkeys working in parent/child form and other form. The case now is when focus on the other form(regular form, not MDI), ProcessCmdKey() doesn't capture keyboard anymore. Which class should I put ProcessCmdKey() in and anything to make it work? Thanks!

namespace myNamespace
{
    public class MDIParent : System.Windows.Forms.Form
    {
 
        public bool NextTab(){...}
        public bool PreviousTab(){...}
 
        protected override bool ProcessCmdKey(ref Message message, Keys keys)
        {
            switch (keys)
            {
                case Keys.Control | Keys.Tab:
                    NextTab();
                    return true;
 
                case Keys.Control | Keys.Shift | Keys.Tab:
                    PreviousTab();
                    return true;
            }
            return base.ProcessCmdKey(ref message, keys);
        }
    }
 
    public class mySecondForm : System.Windows.Forms.Form
    {
        ...
    }
}

Why not just always do base.ProcessCmd Key(ref message, keys); ?
