#firegestures

I use FireGestures with Firefox, and have a mapping that saves the current image the gesture begins on and then closes the tab.  This is handy on sites like tumblr, where I might open a handful of images with the intentions of saving them.

The script, such as it was, looked like this.

var srcNode = FireGestures.sourceNode; var linkURL = FireGestures.getLinkURL(srcNode); if(srcNode.nodeType == Node.ELEMENT_NODE && srcNode instanceof Components.interfaces.nsIImageLoadingContent && srcNode.currentURI)   {   saveImageURL(srcNode.currentURI.spec, null, "SaveImageTitle", false, true, makeURI(srcNode.ownerDocument.location.href), srcNode.ownerDocument);   var tab = gBrowser.mCurrentTab;   if(tab.nextSibling)     gBrowser.mTabContainer.selectedIndex++;   else     gBrowser.mTabContainer.selectedIndex--;   gBrowser.removeTab(tab);   }

It works, up until the latest update of FF or FG. I've spent an hour and a half trying to figure out what broke.  Of course, the FireGestures site isn't responding, so whatever pittance of documentation they have available... isn't.  Even more frustrating, every modification of a script requires one to not only save it from the edit window, but to also back out of the FG options window entirely before it takes effect.  This is really tedious, particularly when you don't really know what you're doing. :D

So I figured I'd try digging around in the extension's code a bit.  After about 10 minutes of browsing, it seems that everything I'm trying to do can be done with internal FireGestures commands:

FireGestures._performAction(null,"FireGestures:SaveImageNow"); gBrowser.removeCurrentTab({ animate: true });

FireGestures 是火狐的一款滑鼠手勢套件，當初一推出即因速度和功能性將 All-in-One Gestures 的用戶搶了過來，其中一樣很少人用到，但功能強大的功能就是腳本手勢。

除了自己寫外，目前腳本手勢可以在官網取得，或者是自己在網上尋找。

以下是自己推薦的幾款：

下一個分頁群組：

    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);

上一個分頁群組：

    var evt = document.createEvent("KeyEvents");     evt.initKeyEvent(       "keypress",       true,       true,       null,       true,  // holds Ctrl key       false,  // holds Alt key       true,  // 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);

雖然只是透過手勢去模擬熱鍵（ Ctrl + ` 和 Ctrl + Shift+`），不過有習慣在使用分頁群組功能的話，這兩個手勢相當有用，畢竟用手勢直覺多了。

例如我是將下一個分頁設為↑→、上一個分頁為↑←、下一個分頁群組設為↓→、上一個分頁群組為↓←。
