The magit-blob-mode enables certain Magit features in blob-visiting
buffers. Such buffers can be created using magit-find-file and some
of the commands mentioned below, which also take care of turning on
this minor mode. Currently this mode only establishes a few key
bindings, but this might be extended.
magit-blob-previous) ¶This command visits the previous blob that modified the current file.
magit-blob-next) ¶This command visit the next blob that modified the current file.
magit-bury-or-kill-buffer) ¶This command buries the current buffer, if that is being displayed in multiple windows and/or when a prefix argument is used. If neither is the case, it instead kills the current buffer.
You might want to bind u to another command. Suitable commands
include bury-buffer, magit-bury-buffer and magit-kill-this-buffer.
