我可以在 Vim 中映射 Alt 键吗? [英] Can I map Alt key in Vim?

问题描述

我尝试映射为将以下行添加到 .vimrc，但它不起作用.我检查了 .vimrc 是否由 Vim 加载.

map

这个映射有什么错误吗?

解决方案

对于 Mac 用户:对于映射 ALT+hjkl，使用生成的真实字符(找出在 INSERT 模式下使用组合的字符)，对于我得到的键盘示例:

==>ª<ALT+k>==>º

等等.在 StackOverflow 上此处找到了解决方案.>

我用它通过 ALT+k\j 上下移动行，在我的 .vimrc 上使用它:

nnoremap ª :m .+1==nnoremap º :m .-2==inoremap ª <Esc>:m .+1<CR>==giinoremap º <Esc>:m .-2<CR>==givnoremap ª :m '>+1<CR>gv=gvvnoremap º :m '<-2<CR>gv=gv

如此处所述.

希望它有用，享受 Vim :)

我最近从 British" 键盘切换到 ABC - Extended" 并注意到此配置无法按预期工作.作为替代方案，我映射了 和 键来执行相同的操作(我猜这也解决了在这个问题的其他答案):

nnoremap <向下>:m .+1 CR==nnoremap <up>:m .-2 CR==inoremap <down​​><Esc>:m .+1<CR>==giinoremap <up><Esc>:m .-2<CR>==givnoremap <down​​>:m'＞+1 CR gv=gvvnoremap <up>:m'<-2<CR>gv=gv

这也是初学者重新养成使用箭头的习惯并学习更有效的 Vim 运动方式来移动代码的好方法.;)

您可以完成转换映射 和 以在标签之间快速移动:

nnoremap 吨nnoremap <right>总吨

或者任何你喜欢的(甚至是一个残酷的，就像我在旅程开始时所做的那样).

I tried to map to as adding the below line to .vimrc, but it doesn't work. I checked the .vimrc is loaded by Vim.

map <Alt-D> <C-D>

is there any error in this mapping?

解决方案

To Mac users out there: for mapping ALT+hjkl, use instead the real character generated (find out which character using the combination while in INSERT mode), for example with my keyboard I get:

<ALT+j> ==> ª
<ALT+k> ==> º

and so on. Solution found here on StackOverflow.

I used this to move lines up and down with ALT+k\j, using this on my .vimrc:

nnoremap ª :m .+1<CR>==
nnoremap º :m .-2<CR>==

inoremap ª <Esc>:m .+1<CR>==gi
inoremap º <Esc>:m .-2<CR>==gi

vnoremap ª :m '>+1<CR>gv=gv
vnoremap º :m '<-2<CR>gv=gv

as explained here.

Hope it's useful, enjoy Vim :)

ADDENDUM BY Dylan_Larkin (2019): For this to work on a Mac, "Use Option as Meta Key" must be turned OFF in Terminal->Preferences->Keyboard

UPDATE 09/2021

I recently switched from a "British" keyboard to "ABC - Extended" and noticed this configuration doesn't work as expected. As an alternative, I mapped the <up> and <down> keys to do the same operation (which, I guess, also solves most of the complexity explained in other answers of this very question):

nnoremap <down> :m .+1<CR>==
nnoremap <up> :m .-2<CR>==

inoremap <down> <Esc>:m .+1<CR>==gi
inoremap <up> <Esc>:m .-2<CR>==gi

vnoremap <down> :m '>+1<CR>gv=gv
vnoremap <up> :m '<-2<CR>gv=gv

This is also a great way for beginners to rewire the habit of using the arrows and instead learn the much more efficient Vim motion way to move around the code. ;)

You can complete your transition mapping <left> and <right> to quickly move between tabs with:

nnoremap <left> gT
nnoremap <right> gt

Or whatever you fancy (even a brutal <NOP>, like I did at the beginning of my journey).
