I have already read all the articles that I could find about how to rebind keys in firefox. I understand the concept of the autoconfig file, have created one for normal settings. But as I understand it I could also rebind keys there with this snippet ``` try { let { classes: Cc, interfaces: Ci, manager: Cm } = Components; const Services = globalThis.Services; const {SessionStore} = Components.utils.import('resource:///modules/sessionstore/SessionStore.jsm'); function ConfigJS() { Services.obs.addObserver(this, 'chrome-document-global-created', false); } ConfigJS.prototype = { observe: function (aSubject) { aSubject.addEventListener('DOMContentLoaded', this, {once: true}); }, handleEvent: function (aEvent) { let document = aEvent.originalTarget; let window = document.defaultView; let location = window.location; if (/^(chrome:(?!\/\/(global\/content\/commonDialog|browser\/content\/webext-panels)\.x?html)|about:(?!blank))/i.test(location.href)) { if (window.Tabbrowser) { // Place your keyboard shortcut changes here // ... // ... } } } }; if (!Services.appinfo.inSafeMode) { new ConfigJS(); } } catch(ex) {}; ``` But the missing piece is the instructions to set the binding for : alt-j : move one char to the left alt-i : move up one line alt-k : move down one line alt-l : move one char to the right The closest I get to understand this is with this other snippet ``` // remap Ctrl-J to downloads (removing it from focusing the browser bar) let search2 = window.document.getElementById('key_search2') search2.remove(); let openDownloads = window.document.getElementById('key_openDownloads') openDownloads.setAttribute("modifiers", "accel"); openDownloads.setAttribute("key", "J"); ``` But in this case I need to know the values to substitute "key_search2" for the corresponding key bindign "key_charleft","key_previouschar","key_charprev","cmd_charprev"? Any information on how to accomplish that would be greatly appreciated, thanks.
