6. Switch and move the buffer
Add the following three lines to the configuration file:
(Global-set-key "/C-x/C-B" 'bs-show); or another key
(Global-set-key "/m-P" 'bs-cycle-previous)
(Global-set-key "/m-n" 'bs-cycle-Next)
The function is Ctrl + X -- Ctrl + B to display the buffer list. You can select. Alt + P to return to the previous buffer, and ALT + n to the next buffer.
In addition, you can use the logo key to display the buffer list. Add the following in the configuration file:
; Switch to buffer-menu, and press the logo key, similar to (m-x + buffer-menu)
(Global-set-Key (KBD "<apps>") 'buffer-menu)

7. Configuration File Modification (Miscellaneous)
