Question

I wish to have a sequence shortcut for the program I’m developing (in C# .net) to access various buttons in the menu system.

For example:
Ctrl + W, O

First, the user would press Ctrl + W, followed by O

Visual studio uses this method for quite a few of it’s menu shortcuts.

When I am editing a menu however, I’m limited to only one shortcut Ctrl + W or just O, I cannot sequence them.

Is this possible to do with the existing framework?

Simply you could do this:

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
  if (previousKeyEvent != null)
  {
    if (previousKeyEvent.Modifiers == Keys.Control && previousKeyEvent.KeyCode == Keys.W && e.KeyCode == Keys.O)
    {
      MessageBox.Show("Ctrl + W then O");
    }
    else
    {
      MessageBox.Show("Not handled");
      previousKeyEvent = null;
    }
  else
    previousKeyEvent = e;
  }
}

Things to consider

• Single key combinations – Handling those without the scope of a
  previous key event.
• A label for showing that you are awaiting the
  user input, just like visual studio.
• Using the ShortCutKeyDisplayString property to show the custom shortcut next to the menu item.
