In theory, you may scan through the titles and click "hide" on each one you know you won't read. The benefit is when you come back later next time, you won't have to scan through those titles again.

This sounds great, except nobody does it, because it's too many clicks.

This chrome extension solves this with keyboard:

[↑] [↓]: go up and down the list

[←]: not interested / hide

[→]: open link (background new tab)

[Enter]: open link (foreground new tab)

[Space]: open comments
