# Description
  User cannot use keyboard shortcuts/combination keys to change PDF page/view.
  e.g., 
       Fn + ← = Home
       Fn + → = End
       Fn + ↑ = Pg up
       Fn + ↓ = Pg down

# Steps to reproduce
  01. Open "https://www.irs.gov/pub/irs-pdf/f1040.pdf" by using plug-in
  02. Use following combination keys to change PDF view/page
       Fn + ← = Home
       Fn + → = End
       Fn + ↑ = Pg up
       Fn + ↓ = Pg down
  03. Select an input field
  04. Use following combination keys to change PDF view/page
       Fn + ← = Home
       Fn + → = End
       Fn + ↑ = Pg up
       Fn + ↓ = Pg down

# Actual result:

Select an input field, and then press "esc". The input field displays "E".
It seems to me that it causes by the same root cause.

As I already modified our implementation, I think the input field displays characters (P, H, E) when uses input functional key is solved. However, I would check again.

(1) The showing of the redundant characters has been fixed. Please refer to "PPB_KeyboardInputEvent" implementation.

(2) Fn + ← = Home
    Fn + → = End
    Fn + ↑ = Pg up
    Fn + ↓ = Pg down

These four keyboard shortcuts are working now.
