使用/设置 Compose 键

介绍

compose 键是键盘用来输入不在键帽上的字符。这样的字母可能是"元音字母变音符号（umlaut）"，"长音符号（macron）"或是字母标音（accents on letters）：

教程已经在多个Kubuntu Hardy Heron 8.04.1系统上测试过了。进一步的信息可以在下列的链接和进一步信息小节找到。

修改对（几乎）所有程序，包括桌面环境、浏览器、OpenOffice.org和众多终端/字符程序（console/text only applications）有效。

如下的教程会设定一个<compose>键，，同时映射到<right logo>键（多数键盘上这个logo 是Windows logo）。

终端设置

To do this properly I'm trying to go the "holistic way" starting with the console:

Reconfigure the console for the used keyboard, and the character encoding. Do this in a text terminal or the console.

$ sudo dpkg-reconfigure console-setup

Follow these steps in the configuration:
- Choose your keyboard (here a default 104 US keyboard)
- If you want the !AltGr key replacement, choose one
- Choose which key you would like your compose key to be mapped to. I use the right logo key.
  I'd much rather like to use the left logo key, but that's not available in the console setting. But in the graphical window environment (KDE Plasma) that is possible.
- Choose the console's encoding, set it to UTF-8
- Choose what character set should be available on the console. I use Combined - Latin; Slavic Cyrillic; Hebrew; basic Arabic
  I guess that selection should give me the wanted characters.
- Choose what type of console output you'd like (do whatever you like, to be safe you can go with the given current defaults)
- A new initial RAM disk for the next boot will be created now.

KDE 3.x 设置

现在我们继续，设置我们的窗口环境（Plasma）。这里用的是Kcontrol或叫 Kubuntu 配置工具，打开的是一样的设置对话框。

启动 系统设置（System Settings）或叫KDE 控制中心（Control Centre）
区域和语言（系统设置）或区域和辅助功能（控制中心） -> 键盘布局
选择你的键盘布局
修改Xkb 选项，选择/启用compose key

KDE SC 4.x 设置

现在我们可以继续，设置我们的窗口环境（Plasma）。这里的描述中用的是系统设置（System Settings），通常能在 Kickoff 菜单中找到：

打开 系统设置
地区和语言
选择键盘布局设置项
在布局标签页，选择启用键盘布局
修改高级选项，选择/启用compose 键

Configuration for Gtk Applications (Gnome, FireFox, etc.)

Gtk (such as also FireFox) and Gnome applications use (on an Ubuntu system) usually SCIM as the input method, not XIM (X Input Method) that relies on the configurations from (X)Compose. Therefore, you will often find that the "a" and "o" macron characters can yield the female/male ordinals "ª" and "º". To still make it work, Gtk applications need to be "told" to use XIM instead.

"One Off" Configuration

For a single application you can do it by just setting the environment variable GTK_IM_MODULE for the application to be launched to xim:

$ GTK_IM_MODULE=xim firefox

More permanently that can be done for a single shell session like this:

$ export GTK_IM_MODULE=xim

This can, of course, also be persisted for a single user in your ~/.bash_profile, or for all users in /etc/environment. This is, however, the less elegant way, the more elegant way follows below.

Persistent Configuration

Copy the setup file /etc/X11/xinit/xinput.d/default to /etc/X11/xinit/xinput.d/xim

$ sudo cp /etc/X11/xinit/xinput.d/default /etc/X11/xinit/xinput.d/xim

Edit the file /etc/X11/xinit/xinput.d/xim and set the input method for GNOME and KDE to xim

...
 GTK_IM_MODULE=xim
 QT_IM_MODULE=xim
 ...

Create a link for the locale all_ALL (or the desired locale only):

$ sudo ln -sf /etc/X11/xinit/xinput.d/xim /etc/X11/xinit/xinput.d/all_ALL

If you are using a Debian-derived distribution use following instead

$ sudo update-alternatives --verbose --install /etc/X11/xinit/xinput.d/all_ALL xinput-all_ALL /etc/X11/xinit/xinput.d/xim 20

After a restart of the X server everything should work.

Optional Tweaking of XCompose Map

Now that you're using XIM, you can further tweak the XCompose input map for further characters, or for characters in more convenient locations, etc.

To do that follow these steps:

Create a ~/.XCompose file, and put the following lines into it:

# ~/.XCompose
 # This file defines custom Compose sequences for Unicode characters

# Import default rules from the system Compose file:
 include "/usr/share/X11/locale/en_US.UTF-8/Compose"

# To put some stuff onto compose key strokes:
 <Multi_key> <minus> <greater> : "→" U2192 # Compose - >
 <Multi_key> <colon> <parenright> : "☺" U263A   # Compose : )
 <Multi_key> <h> <n> <k> : "hugs and kisses" # Compose h n k
 <Multi_key> <less> < p> : "< p>
" # Compose < p

Just log out and in again (no restart necessary), and you can use your new "multi key short strokes" using the compose key to your desire. As you see this even works for creating longer character sequences.

Typing Macrons, Umlauts, Accents, ...

The compose key will be now whatever you have configured it to be, e. g. right logo.

Macrons

compose + shift + hyphen then <vowel >

or

compose + underscore then <vowel >

-->

āēīōū ĀĒĪŌŪ

Umlauts

compose + shift + <single quote> then <vowel >

or

compose + <double quotes> then <vowel >

-->

äëïöü ÄËÏÖÜ

The German Ess-Zet ligature

compose then s and s (twice the "s")

-->

ß

More bindings can be found in /usr/share/X11/locale/en_US.UTF-8/Compose
