作为选项的选项: Vim打印æ，这在我的法语键盘上是正常且预期的 作为元数据的选项: Vim待在那儿，等着事情发生.什么都没有打印.如果我依次按Option键和a键，则只需获取a即可.按任意顺序按Option和a可能会打印á，这很奇怪，而且完全是意外的. 作为+ ESC的选项: Vim打印^[a，表示转义字符后跟字符a".从这些测试看来，如果没有一些假设的黑魔法，Vim将永远不会收到<M->.如果您坚持使用"Option as + ESC" ，似乎您必须将所有自定义<M-something>映射更改为<Esc>something.这可能行得通，但会使使用任何非英语语言撰写任何类型的散文都感到痛苦.我的工作:我保持Option键不变，以便我可以轻松键入œ…«»之类的字符，并为所有自定义映射使用<Leader>(映射到,，请参见:help mapleader).这里有些人喜欢为插件保留它，并提倡一种更简单且可能更安全的方法.inoremap <leader>, <C-x><C-o> "my way (copied elsewhere)inoremap ,, <C-x><C-o> "another wayI noticed that iTerm2 offers the very convenient feature of using "Option key as +ESC" (or as meta, but apparently that's obsolete).I tried them both and the option key works as expected in Bash (set -o emacs mode) and Emacs, but not in Vim. Thus, I can't make use of any "M-" bindings.What I've found is that:if I set option to "+ESC", vim just understands ESC+key, and has no idea I actually meant Meta-key.if I set option to "meta", keys modified with "option" behave just as without a modifier (don't know how to formally test what vim understands from a key combination that I'm typing)."M-" mappings work perfectly in MacVim (7.3.53), but that's outside of a console and not in the scope of this question.I'm interested in how to make those mappings work in Vim, under iTerm2 or Terminal.My specs:MAC OS X Lion 10.7.2iTerm2 1.0.0.20111020vim @7.3.107_0+python26 [though MacPorts] 解决方案 I've downloaded the latest iTerm2 and tried to see what it sent to/what was printed by Vim (i<C-v><M-a>) with the following settings:Option as Option:Vim prints æ which is normal and expected on my french keyboardOption as Meta:Vim stays there, waiting for something to happen. Nothing is printed. If I press Option and a in sequence I just obtain a. Pressing Option and a in some random order may print á, which is weird and totally unexpected.Option as +ESC:Vim prints ^[a which means "Escape character followed by the character a".From these tests it appears that Vim will never ever receive <M-> without some hypothetical black magic.If you stick with "Option as +ESC", it seems that you will have to change all your custom <M-something> mappings to <Esc>something. This may work but it will make writing any kind of prose in any non-english language a pain.What I do: I leave the Option key as it is so that I can type characters like œ…«» easily and I use <Leader> (mapped to ,, see :help mapleader) for all my custom mappings.Some people here like to reserve it for plugins and advocate a somewhat simpler and potentially safer approach.inoremap <leader>, <C-x><C-o> "my way (copied elsewhere)inoremap ,, <C-x><C-o> "another way 这篇关于"M-"表示在iTerm2/Terminal上的vim绑定不起作用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
