Vivaldi Mail’s Quick Reply is perfect for those fast, short replies, and feels like using an instant messenger. By removing the need to switch screens to open the composer window, this feature allows you to respond to emails more quickly.
To send a quick reply:
When you feel like the browser is getting a little sluggish, it’s likely that one or more of the tabs is using a lot of resources. In that case, it might be a good idea to close or at least hibernate the tab(s). To find the resource hogs, simply hover over a tab on the Tab Bar to view their memory usage.
If you don’t see Tab Thumbnails on hover, go to Settings > Tabs > Tab Display > Tab Options and make sure “Show Popup Thumbnails” has been enabled.
There are many ways our community is helping Vivaldi grow – by promoting Vivaldi to potential new users, testing or translating the products and web pages, helping other users with their questions, and more. But we’ve also made it possible to support Vivaldi by making a donation, either a one-time donation or a recurring monthly donation.
When you’re logged out, you can make a one-time anonymous donation, but when you’re logged in you can show off that you believe in our mission and have made a donation.
To get the badge of appreciation:
When someone replies to a topic you’ve commented on on the Vivaldi Forum, then of course you want to see what they say and you click on the notification to be taken to the topic. But some notifications are just informational. In that case, you can mark them read without opening the topic.
To mark a notification as read:
To mark all notifications read, click on “Mark all read” at the bottom of the list.
Web Panels are great for taking a quick glance at a website, but occasionally the mobile-sized view may not be enough. In that case, you can open the current page you have open in the Web Panel in a tab instead.
To open a Web Panel in a tab:
If adding a search widget to your Home Screen on iOS (see Tip #389) is not to your liking, you can still open Vivaldi with a new tab ready to type in a search keyword or a web address.
To open a new tab with focus on the Address Field:
Some websites offer their content in multiple languages. In which language they display the pages in your browser depends on your language settings. Make sure to include all the languages you speak and list them in the order of preference.
To update your list of accepted languages:
Add Language button to select a language you speak.
Even if you can undo some things, it’s better to prevent them in the first place. That’s why on Vivaldi Social, you can choose to be asked to confirm your decision before boosting or deleting posts, and before unfollowing an account.
To enable confirmation dialogs:
Vivaldi keeps the most recent tabs, you either unintentionally closed or have changed your mind about closing, available in a list, from where you can easily reopen them.
To open a recently closed tab in the active tab:
Vivaldi menu and select 
“Recent tabs”.To open a recently closed tab in a new tab:
Closed Tabs tab.
If you have “Switch Tabs By Scrolling” enabled in Settings (see Tip #184), you can switch tabs by using the scroll wheel on your mouse. But did you know, that you can also switch Workspaces like that?
To switch Workspaces:
Having too many icons can sometimes make things confusing. To make it clear what one or the other button on your Vivaldi blog editor’s menus does, you can opt to display text labels instead of icons.
To switch from icons to text:
Options menu in the top right corner. 
In Tip #39 we told you about Keyboard Shortcuts you can use in the Vivaldi Calendar to switch to specific views (Day, Week, Month, etc.). In this tip, we’re introducing you to alternative shortcuts, which allow you to cycle through the views using the same two shortcuts.
To cycle through calendar views, press:
Alt + Page ↑ – to zoom in, and Alt + Page ↓ – to zoom out.Step by step, you can zoom in from Agenda view down to Day view and from Day view out to Agenda view.
Found something interesting on a webpage that you want to save, but an image would convey the message better than text? With Vivaldi, you can take a screenshot of the web page and automatically create a new note with it.
To save a screen capture as a note:
“Capture page” button on the Status Bar.The captured screenshot will be attached to a new untitled note, which you can view and edit in the Notes Panel or Notes Manager.
Single Key Shortcuts are a great way to get things done quickly and efficiently, without needing both hands or complicated finger gymnastics on the keyboard to reach multiple keys simultaneously. For example, you can use Single Key Shortcuts to zoom in and out on web pages.
To enable Single Key Shortcuts, go to Settings > Keyboard > Keyboard Shortcuts.
To zoom in and out, press the following numbers either above the letters on the keyboard or on the number pad:
