g 是几个命令的前缀。例如goto 移动光标，还 gqip 格式化段落。所有以g为前缀的命令的参考在哪里？
【问题讨论】：
:help g
d 是一名操作员。每当它与一个动作结合使用时，它就充当自己：“在这些括号之间删除”、“从这里删除到 EOL”等。另一方面，g 什么都不是：不是运算符，不是命令，不是动议。这只是 Vim 的创建者几十年来一直用作新命令的垃圾箱的一个空槽。如果你能找到一些对你有好处的助记技巧，但这些命令真的无处不在。

Vim 的文档是http://vimdoc.sourceforge.net/。如果您查看 HTML 文档，您会发现 |reference_toc| More detailed information for all commands，其中包括 |index.txt| alphabetical index of all commands，由于一个名为 index.txt 并链接为 index.html 的 doc 文件的不幸怪癖，它实际上并没有导致到你期望它引导的地方。
长话短说，http://vimdoc.sourceforge.net/htmldoc/vimindex.html#g 是您要查找的文档（“以 'g' 开头的命令”）。
或者，在 Vim 中键入 :help *g*。
（抱歉 merlin2011，但您的列表有些不完整...）
应用了一些重新格式化：

【讨论】：
gU{motion} 2 make Nmove text uppercase 到底是什么意思？什么是 Nmove？
gU5e，看看 Vim 把从光标到第 5 个单词结尾的所有内容都变成大写。
打开vim。输入:help g。
