The Power Buttons on this page are in fact BookMarklets that allow you to alter the content of webpages you visit with Opera. To undo the effects of power buttons, simply Refresh or use the standard Reload button.
Note to users: They probably don't work on Framed pages; maximise a frame first before using them.
Note to button creators: It seems javascript wrapped as custom buttons has a 974 byte limit (remember this includes encoding so actual bookmarklet size is smaller than that) - so only 'small' javascript functions can be made into buttons.
It is better to drag buttons to a toolbar rather than to click on them.
These Power Buttons may be useful when you read very long pages. Use the buttons to scroll the page automatically. Press the buttons multiple times to speed up the scrolling. Press Esc key to stop /slow down the scrolling. The FastScroll button is 4 times faster than the Scroll button.
These buttons let you open a Compose Message page and enter the selected addresses from the Contacts panel in the CC or BCC field. They should be placed in the Contacts panel toolbar.
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 another version of the power button where you dont need to stop the page, because it executes the wand first.
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:
Note: the Babelfish translation service does not work on all websites (for example, the Opera Forums' threads cannot be translated).
