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).
This fork does not set any keybindings, only provides the toggle commands. You can define mappings yourself like this:
nnoremap <leader>ll :LToggle " toggle location list
nnoremap <leader>qq :QToggle " toggle quickfix list
Here's how you can set the height (in number of lines) of the spawned window:
let g:lt_height = 10
