The BufExplorer plugin makes it easy to browse and navigate to the various buffers open in a Vim session. It is based on your buffer list. After a bit of coding, your buffer list can start to get a bit out of control. There are surely going to be buffers that you want to close out, delete if you will.
Within the BufExplorer browser you can move your cursor onto a buffer and delete it.
To delete it by unloading the buffer (see :h bd), you can hit d.
To delete it by wiping out the buffer (see :h bw), you can hit D.
If you already have the plugin installed, see :h bufexplorer for more
details.
