-    list: alle geöffneten Buffer werden aufgelistet (ohne Angabe von Argumente wird diese Liste standardmäßig ausgegeben)
-   clear: leert den Inhalt des Buffers (entweder durch Angabe der entsprechenden Nummer des Buffers oder "-merged " für zusammengefügte Buffer oder "-all" für alle Buffer. Ohne Angabe eines Arguments wird der aktuelle Buffer gelöscht)
-    move: Buffer in der Liste verschieben (kann auch relativ sein, z.B. -1); "-" = auf erste Position verschieben, "+" = auf letzte Position + 1 verschieben
-    swap: tauscht zwei Buffer miteinander aus (bei Angabe von nur einem Buffer (Buffernummer/-name), wird der aktuelle Buffer mit dem angegebenen Buffer getauscht)
-   cycle: springt in einer Schleife von einem Buffer zum nächsten, die in einer Liste angegeben werden
-   merge: fügt den aktuellen Buffer mit einem anderen Buffer zusammen (bei einem Chat-Buffer entsteht eine Zusammenfügung von zwei Buffer
-         (Bei der Standardtastenbelegung kann mittels "CTRL-x" zwischen zusammengefügten Buffern umgeschaltet werden)
- unmerge: trennt Buffer wieder voneinander, falls zwei Buffer die selbe Nummer teilen
-    hide: versteckt einen Buffer
-  unhide: macht Buffer wieder sichtbar
-renumber: Buffer werden um nummeriert (Einstellung weechat.look.buffer_auto_renumber muss deaktiviert sein)
-   close: Buffer schließen (Nummer oder Bereich ist optional)
-  notify: setzt den Status der Benachrichtigung für den aktuellen Buffer. Folgende Möglichkeiten bestimmen den Grad der Benachrichtigung:
-            none: keine Benachrichtigung
-       highlight: Benachrichtigung bei hervorgehobenen Nachrichten (Highlights)
-         message: Benachrichtigung bei Nachrichten von Usern + Highlights
-             all: Benachrichtigung bei allen Nachrichten
-           reset: Benachrichtigung auf Standardwert zurück setzen (all)
-localvar: zeigt die lokalen Variablen für den aktuellen Buffer an
-     set: setzt eine Eigenschaft für den aktuellen Buffer
-     get: zeigt eine Eigenschaft für den aktuellen Buffer an
-  number: wechselt von einem Buffer zu einem anderen, mögliche Optionen:
-          '+': relativer Sprung um 'n'-Buffer
-          '-': relativer Sprung, um 'n'-Buffer
-          '*': wechselt zum Buffer mit der Nummer 'n'; nutzt die interne Einstellung "weechat.look.jump_current_to_previous_buffer"
-       -: springt zum ersten Buffer

+renumber: renumber buffers (works only if option weechat.look.buffer_auto_renumber is off)
