CustomWKWebView.swift

TLDR

This file defines a custom subclass of WKWebView called CustomWKWebView.

Methods

performKeyEquivalent(_: NSEvent) -> Bool

This method overrides the performKeyEquivalent method from WKWebView. It checks if the event is a key equivalent for certain modifiers (command, control, and option). If it is not, it calls the super implementation of performKeyEquivalent. It then returns true to prevent a "funk" error sound.

Classes
