Keyboard navigation for menus

[colinmegill]

Replace no-ops with application keyboard navigation. Presently, we satisfy the linter with a no-op.

onKeyPress={() => {}}

without this no-op:

104:11  error  Visible, non-interactive elements with click handlers must have at least one keyboard listener  jsx-a11y/click-events-have-key-events

✖ 1 problem (1 error, 0 warnings)

Or, decide this rule is not necessary.
