+# Access Past Copy Buffer History
+
+Each time you perform a copy (as in copy/paste) within tmux using its built-in
+copy functionality (i.e. `set-buffer` and `save-buffer`), the text that you
+copied to the buffer is recorded in the server's history.
+
+_Note: you may have `Cmd-c` or the mouse configured to copy to a tmux buffer._
+
+So, while `tmux paste-buffer` (or `Cmd-v` if you have that configured) will
+only paste in the most recently copied value to a tmux buffer, you can still
+access more of the history.
+
+Run `tmux choose-buffer` (or `<prefix>:choose-buffer`) to open an interactive
+prompt that lists the tmux buffer history in reverse chronological order (most
+recent to oldest).
+
+You can navigate up and down through these buffers until you find the one that
+contains what you're looking for. Then hit `Enter` and the value will be pasted
+to the current window and pane.
+
+See `man tmux` and search for `choose-buffer` for more details.
