Synopsis: This guide provides practical technical instructions for customizing Opera browser's display settings to improve web accessibility. Written by a disability accessibility expert and editor, the content offers two distinct methods for adjusting text and image sizes: temporary zoom adjustments using keyboard shortcuts (plus and minus keys or Alt+V combinations) and permanent configuration changes through the browser's Tools and Preferences menus. The straightforward approach makes web content more readable for people with visual impairments, older adults experiencing age-related vision changes, and anyone who needs larger on-screen text. While the guide dates from 2009 with updates through 2013, the fundamental techniques remain relevant for users seeking browser-based accessibility solutions without requiring specialized assistive technology - Disabled World (DW).

Introduction

One of the abilities of the Opera browser is a function to not only change the default text size of web pages but also increase image sizes by using the computer keyboard. Opera can resize all aspects of website pages, including font or text size, image sizes, and web page sections.

Instructions to increase the image and font size in Opera:

Press the "+" key, note that in some versions of the Opera browser you may have to also press the "Shift" key, to increase the text size and press the "-" to decrease font size. Each press of either key will increase or decrease the size of the web page text by 10%.

Another method of accomplishing this is to press "Alt" + "V" keys which will bring up the view menu, you can then press the "Z" key to bring up the Opera zoom functions and using the up and down arrow keys you can simply select the font size you require, to finish just press the "Enter" button.

Using the above method the changes to the text size options you made will NOT be remembered next time you open an Opera session. To have Opera use your font preferences each time you use it you will need to follow these instructions to semi-permanently increase or decrease the text size:

a) Click the "Tools" menu using your mouse then select "Preferences" from the menu or press "Ctrl ' and "F12" keys on your keyboard.

b) Click the "Web pages" tab with your mouse or select by pressing "Ctrl" and "Tab" keys until "Web pages" is highlighted.

c) Click the "Page Zoom" options box and select your text zoom size or press the "Tab" key twice to select the page zoom options, then use your up and down arrow keys to select the zoom level you require.

d) Finally click the "OK" button or press "Enter" to return to your Opera browser.

Insights, Analysis, and Developments

Editorial Note: Though modern browsers have evolved since this guide's publication, the principle behind Opera's zoom functionality - giving users direct control over how content appears on their screens - remains a cornerstone of web accessibility. Today's browsers offer even more sophisticated customization options, yet many users still don't know these features exist. The real value here isn't just in the specific keystrokes, but in the reminder that accessibility often starts with the tools already at our fingertips. Whether someone has low vision, experiences eye strain from prolonged screen time, or simply prefers larger text, taking five minutes to adjust browser settings can transform their daily internet experience from frustrating to functional - Disabled World (DW).
