如何调试不起作用的键盘快捷键？

我在使用 XUbuntu 15.10。我注意到一些键盘快捷键无法到达我的应用程序（Sublime Text）。

Ctrl++对应用程序来说是不可见的，而例如++Alt却可以被正确识别。pCtrlAlti

我尝试用 来调试该问题xev，以下是我所看到的结果。

Ctrl++Alt给i我：

KeyPress event, serial 28, synthetic NO, window 0x3e00001,
    root 0xf9, subw 0x0, time 473258, (88,-10), root:(4850,512),

    XLookupString gives 0 bytes:
    XFilterEvent returns: False

但Ctrl+Alt+P给出：

没有KeyPress或KeyRelease为p，而是有一个神秘的KeymapNotify。

我查看过，xfce4-settings-editor但没有发现匹配的键绑定。

我该怎么做？如何找到窃取此组合键的内容？

答案1

我以前也遇到过类似的问题。另一个应用程序已经在使用键盘快捷键，但它没有显示在键盘 > 应用程序快捷键中。因此，它无法重新分配。

在终端中，使用您最喜欢的文本编辑器打开以下内容：

gedit ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml

我假设您想使用ctrl+ alt+ p。搜索带有 的行<Primary><Alt>p并将其删除。现在尝试为 Sublime Text 设置键盘快捷键。
