Fixed bug 4709 - incorrect (not) handling of windows on-screen cursor keys Alex Denisov When using Win10 on-screen keyboard (tooltip.exe), the left and right cursor keys in it do not produce SDLK_LEFT and SDLK_RIGHT events. Windows messages generated by the on-screen keyboard, for some reason, have their scancodes set to zeroes. Here is the log from Spy++: WM_KEYDOWN nVirtKey:VK_LEFT cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:0 fUp:0 WM_KEYUP nVirtKey:VK_LEFT cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:1 fUp:1 Regular physical keyboard produces VK_LEFT (ScanCode:4B) and VK_RIGHT (ScanCode:4D) which are interpreted correctly. With on-screen keyboard, the switch statement in VKeytoScancode() does not check for VK_LEFT and VK_RIGHT, returning SDL_SCANCODE_UNKNOWN, which in turn does not get mapped to anything (because the scan codes are zeroes).
