The Trinity plugin manages Source Explorer, Taglist and NERD Tree, and build them as a great IDE which works like the "Source Insignt".

• Automatic Display of Declarations in the Context Window on the bottom in the (G)VIM window using the Source Explorer: http://www.vim.org/scripts/script.php?script_id=2179

• Symbol Windows For Each File on the left in the (G)VIM window (G)VIM using the Taglist: http://www.vim.org/scripts/script.php?script_id=273

• Quick Access to All Files on the right in the (G)VIM window using the NERD Tree: http://www.vim.org/scripts/script.php?script_id=1658

1. Place the Trinity files (trinity.vim and NERD_tree.vim) in your Vim directory (such as ~/.vim) or have it installed by a bundle manager like Vundle or NeoBundle.
2. Open the three plugins together with :TrinityToggleAll or map these commands to keys in your .vimrc (Settings Example)
