To meet this requirement it is necessary to define proper order of tabulation by setting "tabindex" attribute and also provide the possibility to work with elements (set the checkbox, change value of radio button, submit the button, etc.)
There also quite some tools to test a particular website's accessibility. W3C provides respectively the following list https://www.w3.org/WAI/ER/tools/ and some explanations https://www.w3.org/wiki/Accessibility_testing . Sorry if a bit off-topic :)
Thanks for addition. These tools help a lot, though they are not able to check everything.
I used AChecker in one of the projects.

Thanks for sharing this!
tabindex
is unfortunately indeed often forgotten by the developers, leading also to problems navigating with Tab-button through forms/website in general (additionally to the problem described by you).Thanks for this explanation. It's good to know the tabindex is also important for screenreaders and accessibility issues!
