-Wenn ein Trigger-Callback aufgerufen wird, dann wird folgende Befehlskette ausgeführt:
-  1. Überprüfung von Bedingungen; falls unwahr, beenden
-  2. ersetze Text mittels erweitertem regulärer POSIX Ausdruck (sofern im Trigger definiert)
-  3. ein oder mehrere Befehle werden ausgeführt (sofern im Trigger definiert)
-  4. Beendigung mit einem Rückgabewert (ausgenommen sind modifiers und focus)
+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 modifiers and focus)
 
-Beispiele (die standardmäßig, eingebauten Trigger kann man sich mit "/trigger listdefault" anzeigen lassen):
-  fügt einer Nachricht die Textattribute *fett*, _unterstrichen_ und /kursiv/ hinzu:
+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 "${tg_tag_nick}" "==\*(\S+)\*==*${color:bold}$1${color:-bold}*== ==_(\S+)_==_${color:underline}$1${color:-underline}_== ==/(\S+)/==/${color:italic}$1${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"
+  open trigger monitor and show only modifiers and triggers whose name starts with "resize":
+    /trigger monitor @modifier,resize*

-トリガコールバックを呼び出す際には、以下の順番通りにアクションを実行します:
-  1. 条件を確認; 偽の場合、終了
-  2. POSIX 拡張正規表現を使ってテキストを置換 (トリガに定義されている場合)
-  3. コマンドを実行 (トリガに定義されている場合)
-  4. リターンコードを返して終了 (modifier と focus を除く)
+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 modifiers and focus)
 
-例 (/trigger listdefault でデフォルトトリガを見ることができます):
-  テキスト属性 *太字*、_下線_、/イタリック/ を追加 (ユーザメッセージのみ):
+Examples (you can also look at default triggers with /trigger listdefault):
+  add text attributes *bold*, _underline_ and /italic/ (only in user messages):

     /trigger add resize_big signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show nicklist"
-  設定を 1 時間毎に黙々と保存:
+  silently save config each hour:
     /trigger add cfgsave timer 3600000;0;0 "" "" "/mute /save"
+  open trigger monitor and show only modifiers and triggers whose name starts with "resize":
