When I visit Yahoo! Mail in a desktop web browser, and I am using the "full-featured" and "newest" Yahoo! Mail interface, I don't see a way to mark all emails in all folders as "read."
The only option that I see is to right-click each folder title and then click "Mark as read." However, if you have many folders, this option is not particularly quick.
On a whim, to see if I could at all decrease the total number of necessary clicks, I tried left-clicking each folder title while holding down the ⌘ command key. But this method did not select more than one folder at once, as I had hoped.
Is there a way to mark all unread emails as read? Does a relevant keyboard shortcut exist?

On the far right edge of the inbox folder heading there is an arrow you can click on and select "mark as read" from the options ("mark as read" or "clean inbox"). Doing this actually marks all emails in inbox and all sub-folders of inbox at once, not page by page if you use CTRL+K or other mark as read options
