我的意思是指那种用了gtk，自己拥有一个独立X界面运行的emacs，。
我自己是一直在一个terminal里面运行emacs的，因为X11 terminal比如xterm/rxvt之类的，都会使用X的字体，所以字体配置从来都不是问题，emacs自然会用你为xterm设定的字体。我以前也曾费劲地去搞emacs的中文显示问题，但是后来发现这个意义真的不大，就在xterm里面运行emacs，什么问题都没有了。
因为没有怎么用过不用-nw参数启动的emacs，所以现在想知道那样有X11支持的emacs有什么更强或者更好的特性吗？能带来什么特别的方便吗？对了，可能鼠标事件的响应是要好很多吧，但是我想用emacs的本意可能就是不想经常去摸鼠标吧。

这个...

比如auctex下, 上下标能用不同大小和位置的字体来做fontlock. term里fontlock就只有颜色之分了吧


又比如preview-latex可以在当前buffer里on the fly显示typesetting的效果,公式多的话很方便的, -nw的emacs就不行

再比如 imaxima 可以捕捉inferior maxima的tex输出然后以图片形式显示计算结果的公式

怎么方便怎么用嘛何必放着鼠标不用呢

[哈哈鬼]

大部分时候用鼠标是比较低效率的
能少用就少用，习惯了以后就不想用了，呵呵

X下的Emacs可以用tab呀，多爽……
至于字体，有时候确实也很头疼，term下就爽歪歪
唉
即爱又恨吧！

terminal下面用speedbar不方便，而且独立界面可以定义的快捷键比终端下多，比如Ctrl+Enter，如果是在纯终端下，我甚至不能用Alt来按M- ，只能去按老远的ESC，好麻烦。

我在termianl下能用右边的alt键作M-，左边的不行。

请问这是为何？

[whiz]

不知道，我是个新手....

[pluskid]

这个应该是配置问题吧，因为我在终端下面是只能用左边的Alt，不能用右边的，而且，Alt一般是右边的用得比较多的——M-x 是很常用的嘛。

if you encounter the problem in x terminal emulators then it probably can be solved by some conf mod.
e.g., for xterm add the following line to ~/.Xresources:

XTerm*metaSendsEscape: true

I use urxvt so there is no such problem.

If you mean a virtual terminal, the ones you switch to by (ctrl-)alt-Fx, it might be due to different reasons. If it's due to the keymap you are using, then you may try

loadkeys emacs

which is a keymap that enabled many mod combinations. see

/usr/share/keymaps/i386/qwerty/emacs.map.gz

another probability could be that `alt' is set to modify higher bits. then use

setmetamode esc

to let `alt' send escape sequences

我确实是指的Ctrl-Alt-Fx得到的那种虚拟终端里面。不过，我执行了

loadkeys emacs

之后还是一样，只有左边的Alt能用，右边的不能用。
我又执行了

setmetamode esc

可是问题依旧，是怎么回事呢？:ask

我看了还有一个emacs2.map.gz，我加载那个东西仍然是不行的。

Oh I see. I was thinking you cannot use the left alt as the meta key.

Actually the right alt is reserved as AltGr. to see this, invoke

dumpkeys | grep Gr

and the keycode associated should be 100, which is the right alt key. This 100 can be obtained by running

showkeys

and then pressing your right alt key.

So, to assign the right alt as meta, you can now invoke

echo 'keycode 100 = Alt' | loadkeys

哈哈！谢谢galilette，这下弄好了！不过有几点：
1。是 showkey 不是 showkeys ，我好不容易才从那个程序里面退出来，好像是等一会不按任何键就可以退出了。
2。光echo 'keycode 100 = Alt' | loadkeys是不行的，反正这样好像把键搞得乱七八糟的，我拷贝了/usr/share/keymaps/i386/qwerty/emacs.map.gz并把那行添加进去，在加载他就可以用了！
这下好了！呵呵！谢谢！

:ask: loadkeys 好像要root权限才能执行的，把他添加到哪个文件里面让他开机自动执行比较合适呢？
