I've read the code in unity/services/panel-service.c
about PanelService: close a menu and re-send the keyevent when handling a
    combination Or when we try to open HUD/Dash. Also, close the active
    menu if a new application is opened and focused. (LP: #10905,
    #1234457, #1197071),

but it still does not resolve the problem about PrintScreen key to
snapshot context menu.

The root reason is at the XGrabKeyboard in popup_grab_on_window() of
gtk/gtkmenu.c.

Guys, don't bother yourself any more, as you know linux means freedom, we could get rid of XGrabKeyboard by ourselves:

Title:
  Keyboard shortcuts, window management - Can't use any global keyboard
  shortcuts or hotkeys when applet/menu is open

Status in Ayatana Design:
  Fix Committed
Status in GTK+ GUI Toolkit:
  Won't Fix
Status in Unity:
  Fix Released
Status in “unity” package in Ubuntu:
  Fix Released

Bug description:
  Reproduce scenario :
   - left click on an applet
   - try the ^-Alt arrow to switch desktop

  When an applet contextual menu is opened, you can't switch desktop with keyboard shortcuts.
  Normally,we should have a consistent behaviour in regards with the workspace-selector applet, ie :
   - first ^-Alt-arrow (for the workspace-selector : click), the menu is unfolded
   - second ^-Alt-arrow , we go to the next desktop

  see bug 29894 for not being able to take screenshots when menu is
  open, another symptom of this bug.

  
  ----------------------------------

  Note from Design:

  This is a critical bug, a user should be able to use a global keyboard
  shortcut at any moment, including when a menu is open.  In the
  unlikely case that there is a conflict between the global keyboard
  shortcuts ( see
  https://launchpadlibrarian.net/85352653/Super_key_shutcuts_overlay.png
  ) and the menu keyboard shortcuts, the menu keyboard shortcuts should
  take precedence.
