why nnoremap - not work

[lemon0910]

I'm curious why nmap - works but nnoremap not work

[t9md]

Since its use psuedo keymap <plug>(choosewin). It has to be re-mapped to actual implementation(it's hidden from user of plugin since it's implementation detail).

If you just use nnoremap it try to execute <plug>(choosewin) as if they are sequence of keystrokes which you never want to do I believe.
