Software to fill forms on web pages is almost as ancient as Internet. Strangely browsers’ native features for that are not receiving much attention. I rely on Opera form filling a lot and it saves me plenty of time.
Read on for settings.
Filling in personal information
Tool > Preferences > Wand
There is button for managing passwords here and fields for personal information as well. After you fill in some stuff when you start filling form on any page you get popup suggesting that information as fast input.
You can also tap Down arrow to get a dropdown.
What about larger stuff?
You can only put so much in those personal information fields. Bigger chunks of text are managed via Notes section in Sidebar (F4).
Now you have access to notes in dropdowns and in context menu Right click > Insert Note.
Determine text snippets you use most, save them and never type them again. Easy and efficient.
