Function eventToString

Return a canonical descriptive string for a keyboard or mouse event.

The result also contains a prefix for modifiers if any, for example "x", "F2", "Control+Home", or "Shift+clickright". This is especially useful in switch statements, to make sure that modifier keys are considered and handled correctly:

  const eventName = util.eventToString(e);
  switch (eventName) {
    case "+":
    case "Add":
      ...
      break;
    case "Enter":
    case "End":
    case "Control+End":
    case "Meta+ArrowDown":
    case "PageDown":
      ...
      break;
  }
