A simple vim plugin for toggling the display of the quickfix list and the location-list. Install it with Vundle or Pathogen (I recommend Vundle).
You can set the key mappings for toggling Vim's locationlist and quickfix

let g:lt_location_list_toggle_map = '<leader>l'
let g:lt_quickfix_list_toggle_map = '<leader>q'
By default, they are set to <leader>l and <leader>q, respectively.

let g:lt_height = 10
