Autofocus the prompt to shutdown dialog

[GlasierXplor]

Problem

In previous releases of elementaryOS, I can do the following to shut down:

• Press the power button (which brings up the prompt to shutdown dialog)
• Press the right direction key on my keyboard
• Press "Enter" to shut down my laptop.

I noticed now that the prompt is not autofocused when it is brought up, causing the direction key not to be captured by the dialogue.

Not a nuisance, but I think it is something that will help in a very tiny way for those who don't want to reach for their mice to click on "shut down".

Proposal

Autofocus the prompt to shutdown dialogue when it is brought up.

I have done some tests and noticed the following:

• If there are no windows opened on the desktop (minimising all applications is also considered not having any windows opened, switching to a blank workspace is also considered not having any windows opened), then on pressing the power button the shutdown prompt is focused.
  • However, if the prompt is closed, and the power button is pressed again, the prompt will not be focused.
• If there are any windows opened, then the prompt will not be focused when the power button is pressed.
  • The focus stays within the last-focused window.
