Allow text keystroke 'Y' and 'N' responses to Dialogs

May work in english but not for other languages

Good point.

Possibly the letters could be user-configurable to accommodate the user's language.

Or perhaps some language-neutral keys could be hard-wired to do the job.

Maybe Enter for Yes and Esc for No?

Whatever can free us from having to drag and click the mouse here ...

Ah, I see now that Enter will currently act for 'Yes''.   Thanks!

Esc however is not acting for 'No'.    

Is there a different key active for 'No'?

I observe:

Tab toggles the highlight between Yes and No.

Enter executes the highlighted choice.
