Added shortcuts for CmdInfo (C-x i) and CmdQuickView (C-x q) commands.

There is a difference between CmdInfo and CmdMenuInfo commands:
  * CmdImfo is assigned with C-x i shortcut and changes the mode
    of inactive panel with flip-flop effect.
  * CmdMenuInfo is assigned with panel according with menu: Left
    or Right. There is no flip-flop effect of this command. This command
    must be present in keymap file to show the assigned shortcut in menu.

The above-written is appropriate for CmdQuickView and CmdMenuQuickView commands.
