Opera FAQs, Tips, Tricks & Tweaks

In versions prior to Opera 12, the last line on the page becomes the first line when using keyboard shortcut Page Down or Space. But scroll behaviour was changed in Opera 12 to show last 6 lines due to the following reason.

Some time last year it became very popular to have position:fixed bar on top of sites (examples are Facebook and Twitter). Soon bug reports came trickling in about scrolling in Opera being broken - hiding content. Dozens of reports, including from active, experienced my.opera members but mostly from normal users.

You can use Scroll Marker extension to easily locate the last read line or change the keyboard shortcut action as shown below to bring back old scroll behaviour.

Search keyboard setup for PageDown & Space and change action under browser widget to the following.

Delay, 10 & Go to page,"javascript:(function(){window.scrollBy(0,window.innerHeight-20)})()"

Search keyboard setup for PageUp and change action under browser widget to the following.

Delay, 10 & Go to page,"javascript:(function(){window.scrollBy(0,-window.innerHeight+20)})()"

Currently there is no option to delete data in Opera Link server but you can delete by the following method. The following method is easy & quick compared to this method.

1. Disable Opera Link in all devices.
2. Copy & paste the following code in run box, Win + R to run Opera with a new profile.

   "%PROGRAMFILES%\Opera\opera.exe" -pd %TMP%\opera-link-delete-profile

   
   

3. Enable Opera Link and then enable the items you want to delete from Opera Link server. Wait for synchronization to complete.
4. The following will delete local data and synchronization will delete Opera Link server data.
   • Open manage bookmarks Ctrl + Shift + B, delete all bookmarks and then empty trash.
   • Open notes, delete all notes and then empty trash.
   • Ctrl + T > Delete all Speed Dials
   • Ctrl + F12 > Advanced > Content > Blocked Content... > Delete all blocked sites
   • F8 > ↓ > Delete all typed addresses
   • Ctrl + F12 > Search > Delete all search engines
   • Ctrl + F12 > Forms > Password Manager...> Delete all passwords
   Wait for synchronization to complete.
5. Close Opera.

It will be convenient to have a keyboard shortcut or mouse gesture for the frequently used action instead of navigating through menu and then clicking the desired menu item. For example, to open new private tab one have to click 3 times in the menu Opera Menu > Tabs ans Windows > New Private Tab.

To create keyboard shortcut or mouse gesture, one should know the action code. For example, to find action code for 'new private tab', type new or private in the action field of keyboard shortcut or mouse gesture. Opera will show action code suggestions for that word and you can figure out the action code.

The above way of finding the action code won't work always. For example, you won't find action code for 'fit to width' because action code for it doesn't have neither fit nor width. You can find action code by looking through the menu setup file but it will be time consuming.

I have created a menu setup that will show action code when you click a menu item. Download menu setup and place it inside profile\menu directory. To find action code for a menu item, activate downloaded menu setup Ctrl + F12 > Advanced > Toolbars > Menu setup > Opera Standard Menu (Menu Name & Action Code), navigate through menu and click the menu item. A JavaScript prompt will show action code for the clicked menu item.

The menu setup will also show menu name at the top (highlighted in red) and included menus (highlighted in blue) within square brackets and this will help if you want to edit that menu.

An access key gives you access to a command by pressing a specific key on the keyboard. Access keys appear on the menu with an underline under the shortcut letter. For example, to open the File menu, the access key is F.

Opera automatically generates access keys for the menus, but sometimes they are hard to remember. To change access key, add the ampersand symbol (&) before the letter you want to use as a shortcut in the menu item name. You can modify either menu configuration file or language file.
