How can I make Safari stop webpages from overriding any shortcuts? I sometimes need to edit pages on WikiDot, but WikiDot overrides the ⌃+E shortcut (and many others), which is a system-wide shortcut I often use due to the lack of an end-key on my keyboard.

Is there a way to stop all webpages from overriding any shortcuts?
There are three ways to prevent this behavior on a web page.


Preferred method - Use the settings on the Web App to disable or change shortcut keybindings.
Use a third-party Safari extension that allows you to modify the keybindings for javascript.
Disable Javascript in Safari.
