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

You should :help <LocalLeader>, but: <LocalLeader> is whatever key you’ve set the maplocalleader variable to, or backslash if if you haven’t set it.
