Restrict keyboard shortcuts in TinyMCE editor

Question

Trying to find where to disable individual keyboard shortcuts in the jQuery version of TinyMCE editor. Currently the list of allowable shortcuts is:

• ctrl+z

Answer 1

Even though this has an accepted answer, I would share what I use with tinymce4. You can simply add editor.addShortcut('ctrl+u', "", "") to the init event method within the setupmethod, which will override the added shortcut

Example:

tinyMCE.init({
    // Your options here
    setup: function(editor) {
        editor.on("init", function(){
            editor.addShortcut("ctrl+u", "", "");
        });
    }
})

You can replace any shortcut you'd like to disable with ctrl+u in the above code.
