使用 xdotool 的 Gnome 3 自定义按键绑定

Question

我用来xdotool创建一个简单的键盘快捷键：

$ gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/ name
'Test'
$ gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/ binding
'F3'
$ gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/ command
'test.sh'

-----

$ cat test.sh 
#!/usr/bin/env bash

VAR1="Test123@"

sleep 0.5; xdotool type --clearmodifiers "$VAR1"

问题是at输出中经常缺少该符号 - 是因为它是特殊字符还是我做错了什么？

$ cat /etc/fedora-release 
Fedora release 21 (Twenty One)
$ xdotool --version
xdotool version 2.20110530.1
