How to Delete Multiple Buffers in Vim/NeoVim

I always confuse how to delete buffers from A to B like from 3 to 12. I typically write:

:bd[elete] 3,15

However the true form is:

:3,12bd[elete]

Delete all buffers
```
:%bd[elete]
```
Delete buffers from the current one to the last except last one
```
:.,$-bd[elete]
```
Delete all buffers except current one
```
:%bd|edit#|bd#
```

It may be good idea to map these to some commands and key-bindings:

"~/.vimrc

" Close all buffers but current
nnoremap <C-B>c :BufCurOnly<CR>
command! BufCurOnly execute '%bdelete|edit#|bdelete#'

All done!
