Buffer management

Buffers manage the display of files and other information. Opening a file replaces the content in the current buffer.

Spacemacs Buffer menu

Listing open buffers

SPC b b to select a buffer from a list of buffers

A helm pop-up window appears at the bottom listing all open buffers. The helm popup window also shows recently opened buffers.

Spacemacs - Buffer menu - List Buffers - Helm Mini buffer

Using the buffer menu, SPC b b you can switch to any buffer currently open, especially useful for those buffers that are not currently being shown in a window.

You can also delete any of the currently open buffers when you no longer need them.

Buffer Transient State

SPC b . launches buffer transient state to manage buffers using single character keybindings.

With a single key you can cycle quickly through all open buffers, forward with n or backwards with either N or p.

Use k to kill the current buffer.
