patch 9.2.0609: completion info popup cannot be scrolled with the keyboard
Problem: The info popup shown beside the insert-mode and command-line
completion menu can only be scrolled with the mouse wheel, so
the part below the visible area is unreachable when working
from the keyboard.
Solution: While the completion menu is shown, scroll the info popup with
CTRL-SHIFT-Up/Down (one line), CTRL-SHIFT-PageUp/PageDown (one
page) and CTRL-SHIFT-N/CTRL-SHIFT-P (one line). The menu stays
open and the selected item does not change.
