Fn + F10 可以写出字母“p”。我该如何学习呢？

我最近发现 Fn + F10 可以产生“p”，但仅限于 Geany 或 Mousepad 等文本编辑器。其他功能键（例如 Fn + F9）可以执行锁定屏幕等预期操作。我会发布有关我的 PC 和软件的信息，但我一点也不知道哪些信息是相关的。因此，我没有寻求修复，而是问：我在哪里可以找到相关信息来理解/调试这个问题？

xev显示以下内容：

调试：打开终端并运行xev。现在按下Fn+F10按键。在输出中查找KeyPress和KeyRelease事件，例如，在我的笔记本电脑上Fn+F10是切换蓝牙的键。如您所见，xev将此键报告为XF86Bluetooth。

KeyPress event, serial 39, synthetic NO, window 0x9800001,
