tabindex and unusable buttons/links without mouse

[Sillymak]

Is it possible to add a tabindex attribute to other anchor tags within the app UI? Especially on the user dashboard.

They are present in the login page but missing on other buttons in the app and they can't be navigated to with keyboard.

Also is it possible to add more event handlers other than .click() to these buttons? These buttons are not usable without a mouse. We have not found a way to activate anchor elements using only a keyboard.

Can role=button be added to the divs that are buttons for screen reader clarity?

This is for keyboard-only situations.
