Spacemacs uses Helm as a way to quickly narrow down to a list of options to help you find what you want.  For example, when you open a file, you can narrow down your choices by providing a pattern.

In this example I discover I have quite a few Magit (git client) buffers open.  So, I open Helm Transient State and using 'magit' as the pattern, select all the magic buffers and run an action on them to kill those buffers.

Keybindings
SPC b b  opens the list of buffers (SPC b B if you are using layouts and want to see all buffers)
M-SPC  opens the helm transient state when you have a helm popup open
M-D  kills either all the marked buffers, or the buffer the cursor is currently over
