With bufexplorer, you can quickly and easily switch between buffers by using the one of the default public interfaces:

\<Leader\>bt toggle open / close

To start exploring in the current window, use: >
 <Leader>be   or   :BufExplorer   or   Your custom key mapping
To toggle bufexplorer on or off in the current window, use: >
 <Leader>bt   or   :ToggleBufExplorer   or   Your custom key mapping
To start exploring in a newly split horizontal window, use: >
 <Leader>bs   or   :BufExplorerHorizontalSplit   or   Your custom key mapping
