Disable backspace

In browser have some shortcut.
Press backspace is one, on pressing this go previous page.

I don’t try all the shortcut.

How I can disable all shortcut?


I use this JQuery:
$(document).on(‘keydown’,function(e){var $target=$(e.target||e.srcElement);if(e.keyCode==8&&!$target.is(‘input,[contenteditable=“true”],textarea’))

Note: Until the JQuery is loaded is possible press the backspace!

This JQuery not work until the Jquery is loaded.

Please GDG.
Make a way to disable all shortcut in the “web browser”, without use any JQuery/Javascript.

We’ll see if it’s possible.
