typo in Carousel paragraph

Hi, 
I think that there is a typo at the beginning of the second paragraph of the section "6 Carousel (Slide Show or Image Rotator)" ( [ https://www.w3.org/TR/wai-aria-practices-1.1/#carousel | https://www.w3.org/TR/wai-aria-practices-1.1/#carousel ] ) in the sentence : 
"Ensuring all users can easily control and are not adversely effected by slide rotation is an essential aspect of making carousels accessible." 
"Effected" should be "affected" because the sentence implies that the slide rotation should not negatively change (or affect) the way the users navigate a website. 
Have a nice day!
