Vim的： <leader> h映射速度慢

Question

I am not very good with vimscript, but I am trying to do some custom mappings in Vim. What I want to do is map <leader>h to switch to the previous tab, but when I press <leader> followed by h , it's waiting for another key and doesn't switch quickly. Is there a way to see what mappings are there starting with the "h" key and unmapping them? Or maybe another, more elegant solution?

Thanks, H.

Answer 1

To see all your mappings, type :map . To see what mapping(s) apply to a given prefix, like your h situation, type :map <leader>h .

What's likely happening is that you have some other h -mappings that take multiple characters. Eg, if you also have map <leader>hx , then vim will pause for timeoutlen milliseconds (see :help tm and also ttm ) before trying to honor your shorter <leader>h , in case you're actually trying to type the longer one.

So you'll need to track down where your longer mapping are coming from and possibly remove them.

Answer 2

Thats Because You need to add enter key also :)

let mapleader = "z"
nnoremap <leader>n :tabe<Enter>
