このページのパワーボタンとはOperaで訪問したウェブページの内容を変更するブックマークレットです。パワーボタンによる効果を取り消すには単純に Refresh ボタンまたは標準の更新ボタンを押してください。
注意: これらはフレームで構成されたページではうまく動きません。使用する前にひとつのフレームを最大化してから使用してください。
ボタン作成者への注意: カスタムボタンにできる javascript の長さは最大974バイト以内にする必要が有るようです(エンコードが加わるので実際の javascript の長さはこれより更に小さくなる事を覚えておいてください)。つまり「小さな」 javascript だけがボタンにできるという事です (Opera 9.5 でこの制限は修正されました)。
これらはクリックするよりも直接ツールバーに ドラッグ する方が簡単に利用できます。
これらのパワーボタンはページを自動的にスクロールするためのもので、非常に長いページを読む時に役に立つかもしれません。ボタンを連続して押す事によりスクロール速度を早くする事ができます。 Esc キーを押す事でスクロールを停止またはスクロールスピードを遅くする事ができます。FastScroll ボタンは Scroll ボタンより4倍高速にスクロールします。
これらのボタンはメールメッセージ作成ページを開き、アドレス帳パネルで選択したアドレスをCCまたはBCCフィールドに入力します。これらのボタンはアドレス帳パネルのツールバーに置いてください。
The buttons above rely on a Regular Expression (RegExp) that looks for extensions in the e-mail addresses such as .com, .org, .de, .nl etc. The expression in the buttons contains the top 31 most used extensions and is therefore prone to errors (*). Make sure to verify the CC or BCC field before sending a message!
By limiting the number of extensions the buttons can become more reliable. The examples below only support e-mail addresses ending with .com, .org, .net, .edu, .jp, .uk and .nl:
(*) Errors will occur if one of the selected e-mail addresses contains a common extension (including the dot) before the @ sign, for example john.compton@operamail.com, or if the extension is not recognized, e.g. john.doe@provider.tk.
This button is inspired by the Super Back Button on CustomButtons and does the same thing: when there is no history available, it will try to open either the referrer or the window opener.
These buttons decrease and increase the last number in the URL of the current page by 1:
The following buttons are combinations of the original Rewind and Fast Forward buttons and the ones shown above. The default behavior is the standard Rewind and Fast Forward, respectively, but if these are not applicable the buttons will search for the last number in the URL and change it as previously described.
Rew
Note that the URL increment will always work if the regular Fast Forward is not applicable; the URL decrement can only be used once with this button, for right after the first time the Rewind function will apply again (since there will be a History to go back to).
This button allows a user to type in a phrase and see all occurences highlighted:
The kill button is utterly invaluable. It basically can kill elements on a page. The selected element will be highlighted with a red square, if so this means left-clicking it will remove that element from a page. Press escape or Click kill again to exit the kill mode. This button is useful for things like:
Kill Using the Mark as Spam icon.
Kill Using the Smiley Pacman icon.
Note: You must drag this button up from the page to the toolbar, not click it and add it or it won't work.
This button allows a user to read a password from the Wand. Instructions: use Wand to enter the password into the appropriate field of a web page. Press Stop immediately so that Opera does not proceed to the password protected content. Finally, press the following button:
Here is a variant which invokes the wand, then records and reports the password. You click it instead of the wand, and don't need to interrupt wand execution.
In Google, you can limit your searches to a certain site or domain using the following format:
some_text site:www.example.com
The following button will ask the user for a search string and then perform a Google site search based on the URL of active page.
The button below is an advanced version of the one above. If the search string the user enters starts with 'd ' (i.e., a letter d followed by a whitespace), the search will be limited to the domain of currently active page (for example opera.com rather than www.opera.com, thus also including my.opera.com, people.opera.com etc.)
These buttons will split the current tab into portions of 70% / 30% (horizontal split) or 50% / 50% (vertical split). They can be considered more flexible versions of the Split-Screen Mode button, because they do not minimize other pages, and preserve the position of the splitter when you resize the tab.
Split page (horizontally) Split page (vertically)Press the Back button to return to the original page.
This button will send the page you're curretly viewing to Babelfish and translate the contents to a language of your choice while keeping the page design intact.
The translations you can choose from after pressing the button are:
注意: the Babelfish translation service does not work on all websites (for example, the Opera Forums' threads cannot be translated).
