" Description: Buffer Explorer Vim Plugin
|
|
" Maintainer: Jeff Lanzarotta (delux256-vim at yahoo dot com)
|
|
" Last Changed: Monday, 03 November 2014
|
|
" Version: See g:bufexplorer_version for version number.
|
|
" Usage: This file should reside in the plugin directory and be
|
|
" automatically sourced.
|
|
"
|
|
" You may use the default keymappings of
|
|
"
|
|
" <Leader>be - Opens BufExplorer
|
|
" <Leader>bs - Opens horizontally split window BufExplorer
|
|
" <Leader>bv - Opens vertically split window BufExplorer
|
|
"
|
|
" Or you can override the defaults and define your own mapping
|
|
" in your vimrc file, for example:
|
|
"
|
|
" nnoremap <silent> <F11> :BufExplorer<CR>
|
|
" nnoremap <silent> <m-F11> :BufExplorerHorizontalSplit<CR>
|
|
" nnoremap <silent> <c-F11> :BufExplorerVerticalSplit<CR>
|
|
"
|
|
" Or you can use
|
|
"
|
|
" ":BufExplorer" - Opens BufExplorer
|
|
" ":BufExplorerHorizontalSplit" - Opens horizontally window BufExplorer
|
|
" ":BufExplorerVerticalSplit" - Opens vertically split window BufExplorer
|
|
"
|
|
" For more help see supplied documentation.
|
|
" History: See supplied documentation.
