我正在使用Dell KB216 Wired Keyboard和 Ubuntu。当我按下Fn键时，它应该将光标移动到行尾或行首，但事实并非如此，相反，光标会像往常一样移动，每按一次移动一个字符。
该
Fn密钥对于其他操作（如选择替代密钥功能）非常有用。我还有另一台具有相同 Ubuntu 内核的笔记本电脑，并且
Fn密钥工作正常。Home和End键工作正常，并将光标移动到行尾和行首。我还注意到
Fn+Esc似乎没有切换Fn键，键上有一个锁定图标Esc，不受影响。
知道如何修复该Fn密钥吗？

答案1
我发现这可能是我的键盘硬件问题，有些键盘无法执行某些组合键。例如right arrow+N组合键不起作用。
