-Wenn ein Trigger-Callback aufgerufen wird, dann wird folgende Befehlskette ausgeführt:
-  1. Überprüfung von Bedingungen; falls unwahr, beenden
-  2. ersetze Text mittels einem oder mehreren erweiterten regulären POSIX Ausdrücken (sofern im Trigger definiert)
-  3. ein oder mehrere Befehle werden ausgeführt (sofern im Trigger definiert)

+  arguments: arguments for the hook, depending on hook (separated by semicolons):
+             signal: name(s) of signal (required)

+return_code: return code in callback (ok (default), ok_eat, error)
+post_action: action to take after execution (none (default), disable, delete)
+   addinput: set input with default arguments to create a trigger
+      input: set input with the command used to create the trigger
+     output: send the command to create the trigger on the buffer
+   recreate: same as "input", with option "addreplace" instead of "add"
+        set: set an option in a trigger
+     option: name of option: name, hook, arguments, conditions, regex, command, return_code

+    default: delete all triggers and restore default ones
+    monitor: open the trigger monitor buffer, with optional filter:
+     filter: filter hooks/triggers to display (a hook must start with "@", for example "@signal"), many filters can be separated by commas; wildcard "*" is allowed in each trigger name
+
+When a trigger callback is called, following actions are performed, in this order:
+  1. check conditions; if false, exit
+  2. replace text using POSIX extended regular expression(s) (if defined in trigger)
+  3. execute command(s) (if defined in trigger)
+  4. exit with a return code (except for modifier, line, focus, info and info_hashtable)
+  5. perform post action
+
+Examples (you can also look at default triggers with /trigger listdefault):
+  add text attributes *bold*, _underline_ and /italic/ (only in user messages):
     /trigger add effects modifier weechat_print "${tg_tag_nick}" "==\*([^ ]+)\*==*${color:bold}${re:1}${color:-bold}*== ==_([^ ]+)_==_${color:underline}${re:1}${color:-underline}_== ==/([^ ]+)/==/${color:italic}${re:1}${color:-italic}/"
-  verbirgt die Nicklist auf kleineren Terminals:
+  hide nicklist bar on small terminals:
     /trigger add resize_small signal signal_sigwinch "${info:term_width} < 100" "" "/bar hide nicklist"
     /trigger add resize_big signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show nicklist"
-  speichert die Konfiguration jede Stunde ab:
+  silently save config each hour:
     /trigger add cfgsave timer 3600000;0;0 "" "" "/mute /save"
-  öffnet den Trigger Monitor und zeigt ausschließlich modifier und Trigger an, die mit "resize" im Namen beginnen:
+  open trigger monitor and show only modifiers and triggers whose name starts with "resize":
     /trigger monitor @modifier,resize*
