我已经使用 Lyx 多年了,最基本的快捷键之一是 ^ 在数学模式下不会以文字形式出现,而是在上标位置显示为一个空框。几个月前,它突然开始以文字形式出现。我不知道发生了什么,也不知道该如何修复。我使用的是 Lyx 2.3.1,即最新版本。
因为评论中要求这样做:这里有一个在 Lyx 中显示文字 a^a 的文件:

这里正确显示 $a^a$ :

编译后,两者都显示正确的结果。这两个文件之间的唯一区别在于,在工作文件中,Lyx 将上标代码括在括号中。另请注意,如果您启用了预览,则在您离开该数学模式块后,它将立即正确显示。
答案1
通过更改我的键盘布局解决了这个问题,因此 ^ 按钮不再是一个“死”键,即,不再按两次来获得一个 ^,现在我按一次来获得一个 ^,只有这样它才能在 Lyx 中正常工作。
