What’s a Display Reader?
You will have heard the time period “display screen reader” as you’ve gotten been shifting across the internet. You may even be utilizing a display screen reader at this second to run handbook accessibility assessments on the experiences you might be constructing. A display screen reader is a sort of AT or assistive know-how.
A display screen reader converts digital textual content into synthesized speech or Braille output, generally seen with a Braille reader.
On this instance, I can be utilizing Mac VO. Mac VO (VoiceOver) is built-in to all Mac gadgets; iOS, iPadOS, and macOS methods. Relying on the kind of machine you might be operating macOS on, opening VO may differ. The Macbook Professional that’s operating VO I’m scripting this on doesn’t have the contact bar, so I can be utilizing the shortcut keys in line with the {hardware}.
Spinning Up VO on macOS
In case you are utilizing an up to date Macbook Professional, the keyboard in your machine will look one thing just like the picture under.
You’ll begin by holding down the cmd key after which urgent the Contact ID thrice rapidly.
In case you are on a MBP (MacBook Professional) with a TouchBar, you’ll use the shortcut cmd+fn+f5 to activate VO. In case you are utilizing a standard keyboard together with your desktop or laptop computer, the keys must be the identical or you’ll have to toggle VO on within the Accessibility settings.. As soon as VO is turned on, you may be greeted with this dialog together with a vocalized introduction to VO.
Should you click on the “Use VoiceOver” button you might be nicely in your option to utilizing VO to check your web sites and apps. One factor to bear in mind is that VO is optimized to be used with Safari. That being stated, ensure that when you find yourself operating your display screen reader check that Safari is the browser you might be utilizing. That goes for the iPhone and iPad as nicely.
There are two fundamental methods you should use VO from the beginning. The way in which I personally use it’s by navigating to an internet site and utilizing a mixture of the tab, management, choice, shift and arrow keys, I can navigate by the expertise effectively with these keys alone.
One other frequent option to navigate the expertise is by utilizing the VoiceOver Rotor. The Rotor is a characteristic designed to navigate on to the place you need to be within the expertise.

Utilizing the Rotor
So as to use the Rotor it’s important to use a mixture of your modifier key(s) and the letter “U”. For me, my modifier key’s caps lock. I press caps lock + U and the Rotor spins up for me. As soon as the Rotor comes up I can navigate to any a part of the expertise that I would like utilizing the left and proper arrows.
Navigating By Heading Degree
One other neat option to navigate the expertise is by heading stage. Should you use the mix of your modifier keys + cmd + H you’ll be able to traverse the doc construction primarily based on heading ranges. It’s also possible to transfer again up the doc by urgent shift within the sequence like so, modifier keys + shift + cmd + H.
