Reading https://en.wikipedia.org/wiki/IBM_Common_User_Access and in particular "All operations could be done with either the mouse or the keyboard;", I checked IDLE's dialogs.

The Windows dialogs accessed as common dialogs work correctly. I will assume true for other OSes until told otherwise.

The new Query widget recogizes <Return> for [Ok] but not <Escape> for [Cancel]. My omission, easily corrected.

Search boxes cannot set options with keys. Notepad++ can.

The Options dialog has no key equivalents.

Issue bpo-27620: Escape key closes Query box as cancelled.
https://hg.python.org/cpython/rev/352fc11b9fd2

[terryjreedy]

bpo-27621 is about <Return> invoking [Ok] even when the focus is on [Cancel].

[serhiy-storchaka]

I agree that Esc should always cancel regardless of where the focus is.

Issue bpo-27620: Make htest box respond to <Return> and <Escape>.
https://hg.python.org/cpython/rev/e4a2d78aa6cc

[terryjreedy]

ConfigDialgo.__init__ has commented out key bindings for the buttons, including Esc for [Cancel]. We should establish 'IDLE Dialog Conventions', document (add to README.txt?), and follow consistently.

bpo-27621 is about polishing Query box behavior. It should be generalized to other boxes.
