I am assuming the words here " forward and back through search results" mean moving from one preview to another using keyboard.

If so, the up/down arrows already used for scrolling the screen. Hence we could use the left/right arrow to move through different previews.

We do not have left and right arrow on the preview right now so left/right arrow on keyboard would be equivalent to clicking on each search results one by one.

cc @SimoneThisDot @matthiasmullie for input.

I agree with you on the use of the left/right key. I think that if we add the "keyboard" action we should also add buttons on the screen to provide the same functionality to ALL users.

yeah we will have to add the arrows in the UI if we want to add an ability to switch between previews with keyboard. After playing around with page using my keyboard and screen reader I realize, we cannot assign left and right arrows just for switching between previews as we may have to use it to switch focus from preview to search results and vice versa. As a first step we should make this page accessibility friendly before adding new features. @SimoneThisDot already started a ticket to capture some of the missing things T326641. Once we have done that we can come back to this ticket to add new functionality. I will update the ticket to make it more clear.

I am moving this back to needs design as I want to investigate/discuss if we can do this without adding those buttons on images.

Link to the discussion that happened on this ticket.

Moving this to blocked to evaluate if this feature is necessary.

1. The current data indicates that not many previews are being opened per session.
2. Based on the discussion both solutions right now (up/down arrow vs left/right arrow) has a UX compromise.

So until further data indicates otherwise we should pause on this.
