[Feature]: Keyboard Navigation for the Popup

[brainwo]

Goal or desired outcome of this feature

Allowing a better keyboard navigation instead of pressing Tabs multiple time to select between "Mark as Done", "Mute", and "Remind Me Later" buttons.

Describe the feature

Use Alt shortcuts like in many desktop applications. When Alt button is pressed and holded, underlines will appear under the button keys indicating which key should be pressed to select a button.

If "Mark as Done" has an underlined "D" like "Mark as Done" it means Alt + D can be used to press "Mark as Done" button.
