Tidying up buffersλ︎

Sometimes you want to close several buffers and not just the current buffer with SPC b d.

SPC b b displays a list of open buffers in a popup window.

M-SPC opens the Helm transient menu on the buffer popup window, allowing you to navigate using j and k keys.

M-D will prompt you to kill the buffer the cursor is currently on.

t will mark the buffer the cursor is currently on.

T will mark all buffers listed in the popup.

M-D will prompt you in turn to delete all the marked buffers.


There are a range of actions you can run from the Helm transient state or even when you just have the buffer list popup open.
