Shane Ardell commented on NIFI-13481:
-------------------------------------

I think we could use Escape safely with a modifier, such as Shift + Escape, to 
return back to the canvas. As long as we ensure to avoid single letter keyboard 
shortcuts and common screen reader keyboard shortcuts [1], any modifier + 
Escape should work well.

How many other hotkeys are available? It might be worth considering adding a 
link to the nav menu that opens a modal containing a listing of all keyboard 
shortcuts.

> In the old UI, various pages were shown in a giant modal dialog. The user 
> could simply return to the canvas by hitting Escape. In the new UI, these 
> pages are shown in their own page and not in a modal. In this updated UX, the 
> Escape button no longer makes sense. But we should consider other 
> alternatives (hotkey for back?) to navigate back to the canvas quickly.
