eholdings app menu: Add menu item: Keyboard shortcuts and display a list of keyboard shortcuts in a modal

As a librarian
I want to view a list of shortcut keys I can use for an app.

Add Keyboard shortcuts to the eholdings app dropdown (see mockup)

• Option should be the second option below eholdings app search option

What displays on the keyboard shortcut modal.

• NOTE: Will only show the shortcut keys that are compatible with your Operating System
• Actions: Close a modal/pop-up, Copy, Cut, Paste, and Find do not require any additional development as these are standard browser shortcut keys for these actions.

  Action	OS shortcut	Windows shortcut
  Create a new custom package or title record	Option + n	alt + n
  Edit a record	cmd + Option + e	ctrl + alt + e
  Save a record	cmd + s	ctrl + s
  Expand or collapse an accordion	spacebar	spacebar
  Expand all accordions	cmd + Option + b	ctrl + alt + b
  Collapse all accordions	cmd + Option + g	ctrl + alt + g
  Go to Search & Filter pane	cmd + Option + h	ctrl + alt + h
  Close a modal or pop-up	esc	esc
  Copy	cmd + c	ctrl + c
  Cut	cmd + x	ctrl + x
  Paste	cmd + v	ctrl + v
  Find	cmd + f	ctrl + f
  View keyboard shortcuts list	cmd + option + k	ctrl + alt + k

View keyboard shortcuts list action

• View keyboard shortcuts is additional key to support.
• If user enters cmd + option + k (MAC) or ctrl + alt + k (Windows) shortcut key then the Keyboard shortcuts list modal displays
  AND focus should shift to the modal

Modal Will look similar to what displays when user goes to the User app
