ListToggle

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 windows in your vimrc file:

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.

Here's how you can set the height (in number of lines) of the spawned window:

let g:lt_height = 10
