I use <Space> as my leader key, with a short timeoutlen:
let mapleader = ' '
set timeout timeoutlen=300 ttimeoutlen=5
Sometimes in normal mode, I hit <Space> then hesitate (maybe I changed my mind), letting the timeout expire as I consider my next move.
Normally this would trigger the default <Space> behavior, moving cursor to the right. To prevent this, I've added:
nnoremap <Space> <Nop>
The problem with this is, after the timeout has expired, I can't reinitiate a leader key-sequence until I run some (any) other command, such as hitting Esc. It's as if I need to break out of the <Nop> with some intervening command.
For example, with nnoremap <leader>j <Plug>(foo),
- I type
<Space>and let the timeout expire - then I type
<Space>jexpecting it to run<Plug>(foo), but it does nothing - I hit
Esc - I type
<Space>j--> Vim runs<Plug>(foo)
If I change my mapleader to \ and do map <Space> \, I don't have this problem.
What's causing this timeout/Nop behavior? Is there a way to fix it, or should I use the \ workaround?
Update
This appears to be a known (recent?) bug.
