firegestures to control keyboard shortcuts

[charliedz]

also,

new to extension and script programming, but have had programming experience in general.

does anyone know how to use firegestures to control keyboard inputs? for example cmd + alt + y ?

from firegestures site, the key event script doesn't make much sense to me.. nothing but false next to diff mod keys?

would really appreciate any leads, as i think this should be relatively simple.

thanks!

var evt = document.createEvent("KeyEvents");
evt.initKeyEvent(
"keypress",
true,
true,
null,
false, // holds Ctrl key
false, // holds Alt key
false, // holds Shift key
false, // holds Meta key
evt.DOM_VK_F5, // presses a special key, @see http://mxr.mozilla.org/mozilla/source/d ... yEvent.idl
0 // presses a normal key, e.g. "A".charCodeAt(0),
);
document.documentElement.dispatchEvent(evt);

yes not straightforward at all unless you know the lingo
see list codes here ...
http://mxr.mozilla.org/mozilla/source/dom/public/idl/events/nsIDOMKeyEvent.idl

as I understand it ...
send an "A"
"keypress", true, true, null, false, false, false, false, 0, "A".charCodeAt(0)
send "F5"
"keypress", true, true, null, false, false, false, false, evt.DOM_VK_F5, 0
send "^a"
"keypress", true, true, null, true, false, false, false, evt.DOM_VK_CONTROL, "A".charCodeAt(0)

i can't get it to work either

It's quite easy.. I decided to sign up to this forum just to share this for future requests (it came up high when I looked for it on Google):

ctrl + alt + y would translate to

Code: Select all

var evt = document.createEvent("KeyEvents");
evt.initKeyEvent(
  "keypress",
  true,
  true,
  null,
  true,  // holds Ctrl key
  true,  // holds Alt key
  false,  // holds Shift key
  false,  // holds Meta key
  false,  // presses a special key, @see http://mxr.mozilla.org/mozilla/source/dom/public/idl/events/nsIDOMKeyEvent.idl
  "y".charCodeAt(0)  // presses a normal key, e.g. "A".charCodeAt(0),
);
document.documentElement.dispatchEvent(evt);

I created this code to switch to the next tab group (in Firefox 4)

Code: Select all

var evt = document.createEvent("KeyEvents");
evt.initKeyEvent(
  "keypress",
  true,
  true,
  null,
  true,  // holds Ctrl key
  false,  // holds Alt key
  false,  // holds Shift key
  false,  // holds Meta key
  false,  // presses a special key, @see http://mxr.mozilla.org/mozilla/source/dom/public/idl/events/nsIDOMKeyEvent.idl
  "`".charCodeAt(0)  // presses a normal key, e.g. "A".charCodeAt(0),
);
document.documentElement.dispatchEvent(evt);

Good luck all!

Any idea how to get ctrl+tab to operate properly? This is something I could never figure out. Sending the keypress event is easy enough (will immediately focus the next tab) but getting the thumbnail previews to stay open to toggle through them is something else...

As long as this thread was re-opened fairly recently, I thought I'd ask a question. Not being too bright I don't know much about this script stuff, but I'm trying to get FireGestures to send a key event of a simple "." (It opens the keyboard shortcuts at FastMail's webmail.) The following is what I have (based on trying to understand the information in this thread:

var evt = document.createEvent("KeyEvents");
evt.initKeyEvent(
"keypress",
true,
true,
null,
false, // holds Ctrl key
false, // holds Alt key
false, // holds Shift key
false, // holds Meta key
false, // presses a special key, @see http://mxr.mozilla.org/mozilla/source/d ... yEvent.idl
".".charCodeAt(0) // presses a normal key, e.g. "A".charCodeAt(0),
);
document.documentElement.dispatchEvent(evt);

It doesn't seem to work. What did I do wrong ?

Is it possible to create gestures specific to a web page?

I'm looking at creating gestures just for Google Reader, eg. a gesture to trigger Mark All As Read.

Bump.

It seems firegestures' script works on the chrome xul rather than the document itself (you can see it with alert(location.href);). So keys for Firefox (such as Ctrl-S for save) works but not for a website's keyboard shortcuts. Therefore you have to change 'document' to 'window.content.document' (saw it in the Copy Title script).

So I managed to send the keys 'Shift-n Shift-o' (open next subscription) to Google Reader with the following script:

Code: Select all

var evt = window.content.document.createEvent("KeyEvents");
evt.initKeyEvent("keypress",true,true,null,false,false,true,false,0x4E,0x4E);
window.content.document.dispatchEvent(evt);
var evt2 = window.content.document.createEvent("KeyEvents");
evt2.initKeyEvent("keypress",true,true,null,false,false,true,false,0x4F,0x4F);
window.content.document.dispatchEvent(evt2);

0x4E is equivalent to the value of 'n'.charCodeAt(0) or 110 (see the Mozilla page for the codes). I tried using the number and/or formula, but having the 2 hex codes in the above script made it work. Hope it works for you!

Beautiful ! Thanks so much for your help !!

Just a thought. I don't know FF api terribly well, but bookmarklets use straight up javascript, which is quite handy for a ton of features/functions. There's some handy bookmarklet tools and creators out there. You can set a hotkey to any bookmarklet (google it) and have your gesture activate the the hotkey (the send key script above). This enables your bookmarklet to be cross browser compatible, and each browser has a way to activate bookmarklets with hotkeys and/or gestures.

travis_san:
As for control Tab, there's some scripts that access the firefox api directly. I'd suggest working with those:

Yes, most certainly! It's always worth looking at the available scripts (link above) and see if they have code you can use. In one of them had some code that I modified.
First line gets the url. Second is a javascript function to see if substring is in string. If not, it'll return "-1"
Replace 'google' with whatever domain you're working with.

I have multiple domain specific features, so I used a bunch of if else statements.

const URL = window.content.location.href;
if(URL.indexOf('google')>=0){
// Run your domain specific code here
}

Can someone post what CTRL-ALT-TAB would be?

FireGestures.sendKeyEvent({ ctrl: true, altKey: true, key: "tab" });

doesn't seem to work. I am trying to get the following extension to work with Firegestures:

Try running the following code with FireGestures, then use the shortcut to alert the Focus Last Tab command.

Code: Select all

function getCommand(event) {
  window.removeEventListener("command", getCommand, true);
  event.preventDefault();
  event.stopPropagation();
  alert(event.originalTarget.getAttribute("oncommand"));
}
window.addEventListener("command", getCommand, true);

And there is no altKey property in the FireGestures API.

http://www.xuldev.org/firegestures/makescripts.php

Code: Select all

FireGestures.sendKeyEvent({ ctrl: true, alt: true, keyCode: "DOM_VK_TAB" });

[techer]

Thanks, morat.
I just used the following code that you provided and it worked:
FireGestures.sendKeyEvent({ ctrl: true, alt: true, keyCode: "DOM_VK_TAB" });

I didn't use the other code. However, what would that do? Should I use it? What's the advantage?
function getCommand(event) {
window.removeEventListener("command", getCommand, true);
event.preventDefault();
event.stopPropagation();
alert(event.originalTarget.getAttribute("oncommand"));
}
window.addEventListener("command", getCommand, true);

The purpose of the code snippet is to easily extract commands.

Instructions:

1. open about:config
2. set devtools.chrome.enabled to true
3. tools > web developer > scratchpad
4. environment > browser
5. edit > paste (i.e. copy and paste code above)
6. execute > run

Examples:

7. page info menu item in tools menu

Code: Select all

BrowserPageInfo();

7. paste & go context menu item in location bar

Code: Select all

gURLBar.select();
goDoCommand("cmd_paste");
gURLBar.handleCommand();

7. ctrl+alt+tab shortcut

Code: Select all

focuslasttab.swap();

The trick does not work for all user interface elements.

You could also use the label of the menu item to execute the command.

Code: Select all

var label = "Focus Last Tab";
document.getElementsByAttribute("label", label)[0].doCommand();

What's the advantage?

Sometimes the FireGestures.sendKeyEvent function does not work.
