在emacs lisp中利用侧扫手势

Question

我想在emacs中使用两个手指侧滑的手势。对于向上和向下滑动，它们被绑定到[mouse-4]和[mouse-5]。还有没有两个手指侧扫的绑定？如果没有，是否有任何事件会触发two finger mouse移动？谢谢。

听起来你好像在问mouse gestures，或多或少。如果是这样，那么答案是肯定的。strokes-mode支持鼠标手势:库strokes.el和次要模式Emacs就是为了做到这一点。下面是文档字符串：

切换笔划模式，这是一种全局次要模式。使用前缀参数ARG，如果ARG为正则启用Strokes模式，否则禁用该模式。如果从Lisp调用，则在省略ARG或nil的情况下启用该模式。

Strokes are pictographic mouse gestures which invoke commands.
Strokes are invoked with S-down-mouse-2.  You can define
new strokes with M-x strokes-global-set-stroke.  See also
M-down-mouse-2 for `complex' strokes.

To use strokes for pictographic editing, such as Chinese/Japanese, use
M-x strokes-compose-complex-stroke, which draws strokes and inserts them.
Encode/decode your strokes with M-x strokes-encode-buffer,
M-x strokes-decode-buffer.
