What separates NVDA from a screen reader like VoiceOver is that NVDA is a modal screen reader which means that when you’re in VoiceOver, you’re kind of always in the same mode. In order to this, you just need hit the Left and Right arrow keys. The word “Udacity” will probably be pronounce it in a weird way and so they might navigate through the individual characters to see how it is actually spelled. You can also move by individual character too and this is useful for screen reader users when they land on a word that the text-to-speech software may pronounce poorly. If you hit the Down arrow key, you’ll simply move down in the next paragraph of text. You can also move by line by pressing the Up and Down arrow keys. Pressing the H key will move you forward through the headings while SHIFT + H will do the opposite and move you backwards. When most screen reader users land on an unfamiliar document, they are going to navigate it by heading and in order to do that in NVDA, you need to press the H key. This video from Rob Dodson will give you a brief tour of how to navigate the page using NVDA: There’s a few other options in this dialog such as always show the dialog when it starts, or start NVDA when you open up Windows. But this dialog also lets you map it to the Caps Lock key, which is quite helpful if you’re on a laptop. Similar to a VoiceOver on the Mac, NVDA has kind of like a special NVDA modifier key, which normally is mapped to the Insert key. In order to fire it up, you just need to press CTRL + ALT + N so remember these basic key combinations whenever you want to launch this application on your computer.
They get their money through donations so if you have the means to, and you like NVDA, you can consider donating before you download it from their website: As you go through the download form, there’s an option there to do a donation if you would like and then you can just click the download button to get the application. The nice thing about this tool is that it’s free and open source project. NVDA, which stands for “non-visual desktop access”, is a free screen reader for Windows. Looking for a good screen reader? Then you might have probably heard about NVDA.
