是否有任何提示或技巧可以轻松选择（g）Vim的全向完成弹出的第一个单词？

标签： vim word-completion

例如，如果我写<?ph

可能会弹出以下单词（php会在菜单中突出显示，但不会显示在代码中）：

php
phrase
phrases

如果我点击 Tab 或 CTRL + N ，它就会"Back at original."

如果我按 Shift + Tab 或 CTRL + P ，它会转到phrase。

虽然菜单中突出显示了php，但如果按下输入ph则无法完成。

我不确定这是否是Vim中的正常行为或我的.vimrc有什么问题：

有没有办法立即选择第一个单词？

使用ctrl-y选择列表中当前突出显示的选项。 ctrl-n和p将遍历下一个/上一个列表，但是y将选择当前。

答案 1 :(得分：3)

在您的.vimrc中，您已将completeopt选项添加为“最长”：

set completeopt=menu,preview,longest

这意味着omni completion只能填充所有可能匹配项的最长公共子字符串。如果你只使用:set completeopt=menu,preview，那么vim应该在使用omni completion时选择第一个匹配。
