I have a couple of decades experience using Emacs, so the Emacs-like keybindings for text editing on Mac OS X are very nice. Unfortunately, some websites (ahem) choose to override these with Javascript. For example, one of them makes controlB insert the text **strong text**, rather than going back one character.

Is there any way to make Safari ignore Javascript keybindings that try to remap the standard OS X keybindings?

  • I don't know any general way to do that, but you could use GreaseKit to disable the WMD shortcuts. See Is there a way to disable the hotkeys? - Meta Stack Overflow.

  • Thanks for the link! It's frustrating to see that they think it's fine just because people didn't complain enough. (I've been using SE sites for years and I didn't realize I needed to start complaining on day 1 for my voice to be heard.) I'm hesitant to add any web browser extensions, though, since the first part of any web browser issue diagnosis is "disable all extensions".

    I'm with Ken. I personally can't count how many times I've had to use "undo" because my hands forgot I was on an SE site :S

  • I was going to suggest that you could disable javascript... It fixed your problem, but it created a new one — I could no longer post comments on StackExchange... =P

    Is this question about the site here? or about disabling javascript everywhere? I could move it to our meta as a bug report, but there's already several requests for this site wide. meta.stackexchange.com/questions/3245/…

Here is Rob W's script from meta, updated to only block cntrl-* and fixed so that it works with NinjaKit which is a safari extension for running user scripts.

(function () {
    var p = document.getElementById('wmd-input');
    console.log("wmd-input:" + p);
    if (p) {
        p = p.parentNode;

        function ignore(e) {
            if (e.ctrlKey) {
        p.addEventListener('keydown', ignore, true);
        p.addEventListener('keypress', ignore, true);
        p.addEventListener('keyup', ignore, true);

It's been a while since I've used it, but the Privoxy proxy server has the feature to modify javascript to change behavior. If you're willing to run a proxy server, that is an option.

I did look (though not exhaustively), and didn't see a browser plugin that rewrote content (xml, html, CSS, or javascript) like privoxy does. In Privoxy's web page, look for the js-annoyances filter. That is where you'll find examples of rewriting javascript.

Perhaps there's a more modern implementation in the form of a browser plugin that provides a similar feature, but privoxy used to work fine for this use case.
