Problem
There's no default button indicator.
New file dialog doesn't respond to Enter key. It's naturally expected that pressing Enter on this dialog will activate the "Create" button's function.
The Esc key does indeed seem to "Cancel" the dialog; this is great! Alt+F4 (which also commonly closes dialogs; in Windows at least) actually closes the entire application.
Pressing the Tab key to move focus between dialog elements doesn't actually do so. Currently it affects the editor. See Issue #104.
Focus is indicated on the filename field, which is good.
Solution
Show current focus at each element that is focusable.
Process navigation keys (Tab, Shift-Tab, Enter, Alt+F4?, more?) by showing and acting on focus.
