Because each platform defines values of keys differently, V provides its own symbolic set of key code values. V uses the standard ASCII values for the normal printing keys below the value 0x80. The following are the symbols defined for other key codes:
VKM_Shift VKM_Ctrl VKM_Alt
vk_BackSpace vk_Tab vk_Linefeed
vk_Return vk_Pause vk_Escape
vk_Delete vk_BackTab vk_Home
vk_Left vk_Up vk_Right
vk_Down vk_Page_Up vk_Page_Down
vk_End vk_Insert vk_KP_Enter
vk_KP_Home vk_KP_Left vk_KP_Up
vk_KP_Right vk_KP_Down vk_KP_Page_Up
vk_KP_Page_Down vk_KP_End vk_KP_Insert
vk_KP_Delete vk_KP_Equal vk_KP_Multiply
vk_KP_Add vk_KP_Subtract vk_KP_Decimal
vk_KP_Divide vk_space vk_asciitilde
vk_KP_0 - vk_KP_9
vk_F1 - vk_F16
