Summary 0004733: TJvDesignSurface: Ctrl-Left/Right/Up/Down and Shift-Left/Right/Up/Down on Windows
Description With D2007 the Ctrl-Left/Right/Up/Down and Shift-Left/Right/Up/Down do not work on the design panel (TJvDesignSurface) when is in active mode because the panel does not intercept the "Special Keys" during the WM_KEYDOWN (VK_LEFT, VK_RIGHT,
Steps To Reproduce
Additional Information In D2007 the message management loop calls the IsKeyMsg method. IsKeyMsg
does not pass on the original key message, but it adds an offset (CN_BASE) to
the message ID to turn the original Windows message into a VCL message.
So, WM_KEYDOWN becomes CN_KEYDOWN, WM_CHAR becomes CN_CHAR, and so on.

For this reason, in order to intercept the special keys the CN_KEYDOWN
and CN_KEYUP should be checked in the JvDesignSurface unit.

Please, find attached the proposed patch I added to the above unit officially released in JVCL 3.36 (look for GpCaretti)
