I've been trying to figure out what these back and forward errors are meant for in gmail search view. They seem to always remain in a disabled state while the 'Done' button is always enabled. I thought they were for navigating between long search keywords but that doesn't seem to be the case either. Even if they aren't for that purpose, is it a good idea to have these arrows to shift cursor between keywords?
Btw in gmail compose view, these arrows are meant to navigate between fields.
