How can I use GreaseMonkey to give the browser back the “/” key?
Question
Lots of web pages seem to use the / key for searching. I'd like to disable that because 100% of the time I want to use / to search in the page in FireFox. Is there a way I can override this behavior with GreaseMonkey or dotjs?

If you set
addEventListener()Doc onwindowand use "event capture", you will catch 99% of what the page tries to do. (Not counting plugins like Flash)You can't be sure if the page fires off of
keydown,keyup,keypress, or some combination, so interceptkeydown(the typical event used) andkeyup. But, if the page fires off ofkeypress, then blocking the event may require this kind of technique . This is because thekeypressevent, on<body>, bubbles up to trigger Firefox's in-page search, but there is no way to (re)trigger that search from javascript (for security).Fortunately, your two sample sites do not require any drastic measures.
Event constants, like
DOM_VK_SLASHare great, but they are still pretty much Firefox-only. From this question's tags (dotjs), it is not clear if you mean for this to work on Chrome, too.
Putting it all together, this complete script works:
// ==UserScript==
// @name _Nuke the forward slash on select pages
// @include https://github.com/*
// @include https://wiki.jenkins-ci.org/*
// @grant GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
introduced in GM 1.0. It restores the sandbox.
*/
//-- "true" tells the listener to use capture mode.
window.addEventListener ('keydown', blockSlashKey, true);
window.addEventListener ('keyup', blockSlashKey, true);
/*-- Don't block keypress on window or body, this blocks the default
page-search, too.
window.addEventListener ('keypress', blockSlashKey, true);
*/
function blockSlashKey (zEvent) {
var FORWARD_SLASH = 191; // For keydown and keyup
var ASCII_SLASH = 47; // For keypress
if ( zEvent.which === FORWARD_SLASH
|| (zEvent.which === ASCII_SLASH && zEvent.type == "keypress")
) {
zEvent.stopPropagation();
}
}
Note: This script seems to work well on the two sites you listed, in both Chrome and Firefox. And, it will not stop the typing of / into inputs or textareas. But, there is a tiny chance that it might cause some sites to not fire other events on the / key.
If that happens, then use checks like zEvent.target.nodeName == "BODY" to restrict blockSlashKey() 's operation.

This Greasemonkey script work on Firefox
// ==UserScript==
// @name Disable slash key on page
// @namespace test
// @include https://github.com/*
// @include https://wiki.jenkins-ci.org/*
// @grant none
// @version 1
// ==/UserScript==
document.addEventListener('keydown', function(event) {
if (event.keyCode === event.DOM_VK_SLASH) {
event.stopPropagation();
}
}, true);
