如何在文档中阅读vim的关键含义

Question

I'm trying to understand the following vim help.(:help Voom)

<C-Up>, <C-Down> move node or a range of sibling nodes Up/Down.
<C-Left>, <C-Right> move nodes Left/Right (promote/demote).
(If the above CTRL mappings are not recognized by your Vim, you can also move
nodes Up/Down/Left/Right with <LocalLeader>u/d/l/r .)

The C-Up may means Ctrl-Up. But it can NOT work. (I don't know why). But, what's the means? It means <localLeader>+u will get the same result as C-UP. I don't know what's the key of <LocalLeader>

Answer 1

默认情况下，localleader映射到\\ （反斜杠）

Answer 2

您应该:help <LocalLeader> ，但是： <LocalLeader>是已将maplocalleader变量设置为的键，如果未设置，则反斜杠。

Answer 3

The <c-xx> combinations do all refer to <ctrl-xx> keys. But those keys are not mapped properly by most terminals. So you can use those combinations in gvim, but not in terminal vim.
