Mapping to turn off search highlighting

[lifeBalance]

I have the following mappings:

let g:which_key_map['t'] = {
\ 'name' : '+toggle' ,
\ 'n' : [':set invnumber'              , 'line numbers'],
\ 'N' : [':set invrelativenumber' , 'relative line numbers'],
\ 'h' : [':noh'                              , 'No highlighting']
\ }

Toggling the numbers works flawlessly, but turning off the search highlighting does not.

Ok, I found the way. :

" Toggle stuff
nnoremap <silent> <leader>th :noh<CR>

let g:which_key_map['t'] = {
  \ 'name' : '+Toggle' ,
  \ 'n' : [':set invnumber'            , 'line numbers'],
  \ 'r' : [':set invrelativenumber' , 'relative line numbers'],
  \ 'l' : [':set list!'                        , 'Whitespace characters'],
  \ }

let g:which_key_map.t.h = 'No Highlight'

The mapping is created outside vim-which-key and then the description is added to the dictionary, under the key t.
