如何通过名称找到特定的自定义键绑定？

我可以通过以下方式检索自定义键绑定列表：

gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings

返回类似如下的内容：

['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/', '/org/gnome/settings-daemon/plugins/media keys/custom-keybindings/custom1/', '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom2/']

但我想通过名称了解目标键绑定？即shutter-><primary><shift><alt>a

我想出了一个简单但不方便的方法：

gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-  
keybinding:/org/gnome/settin‌​gs-daemon/plugins/media-keys/custom-  
keybindings/custom0/ name
// return the name like `shutter`


gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-  
keybinding:/org/gnome/settin‌​gs-daemon/plugins/media-keys/custom-  
keybindings/custom0/ binding
// return the binding like `<primary><shift><alt>a`

有人知道其他优雅的解决方案吗？

通过名称查找键绑定的小脚本

使用快捷键运行下面的脚本时，它将输出键绑定姓名作为参数。例如：

$ python3 '/home/jacob/Bureaublad/find_keybinding.py' rename
> '<Primary><Alt>r'

如何设置

  • 将以下脚本复制到一个空文件中，并将其另存为find_keybinding.py

  • 通过命令运行：

    python3 '/path/to/find_keybinding.py' <shortcut_name>

解释

信息位于输出中

dconf dump /

在自定义键盘快捷键上，这将输出如下部分：

[org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom9]
binding='<Primary><Alt>r'
command='/home/jacob/.local/share/nautilus/scripts/change_name'
name='rename'

正如你所见，我们需要上面两行

name='rename'

...因此脚本输出该行，从binding=

剧本

#!/usr/bin/env python3
import subprocess; import sys
key = "/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/"
# read the output from dconf dump /, split into lines
ls = [l for l in subprocess.check_output(["dconf", "dump", key]).decode("utf-8").splitlines()]
# find line corresponding to searched name, print two lines higher
print(ls[ls.index([l for l in ls if "name='"+sys.argv[1] in l][0])-2].replace("binding=", ""))

此外

...您可以创建目录~/bin（如果它尚不存在）并将脚本保存在那里无延伸， 和使其可执行。注销并重新登录，然后只需：

find_keybinding <name>

会做

对于自定义键，请尝试：

for i in $(gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings | awk -F"'" '{ for (i=2;i<=NF;i+=2) print $i }'); do
    echo "$(dconf read ${i}binding) $(dconf read ${i}name)"
done

对于其他键，请通过以下命令进行 grep：

for schema in $(gsettings list-schemas | grep -E 'keybindings|media-keys')
do
    gsettings list-recursively $schema
done
