Quickly delete sockets from menu switch, index switch, capture attribute with a shortcut

That would be nice. But, in my opinion holdinga a modifier key, and then clicking a button is redundant. So, it should either :

• remove the socket with some Modifier key + mouse button ( this should be customizable)
• Or, show the "-" button on mouse over, and then user can click that without modifiers.

If you need first show the button with modifier, and then click, it one step too much.
