wycats's "disallow insert mode" An explanation from vguerci@github: Insert mode can be entered in nerdtree not sure the exact sequence / reason, but i guess that involve using mouse (sounds weird, a bug?) : - open nerdtree, select a buffer, enter insert mode in buffer. - select nerdtree buffer with mouse, you're in insert mode. ...then you can easily get E21, E382 errors.
