Что касается команды External action. Я порылся в архивах my.opera.com и нарыл кое-какое объяснение:
В ответ на "что делает команда external action?":
"Nothing. It's what Opera writes for a drag-and-drop button when it can't decode the action which was there. For example, if you include an extra quote. (Kind of along the same lines as "illegal-url-21".)
Actually, "External action" doesn't do anything. When Opera can't figure out what a drag-and-drop button is supposed to be, it'll write "External Action". Example, if you accidentally include quotes in the action.
If I include two buttons below, the first with the action as "Back" (with the quotes) ...
button
and the second without the quotes ...
button
The first button will list as "External action" and the second will list properly.
Вообще это чисто "кнопочная" команда и на функциональность влиять не должна.
