For windows terminal (but no wxt on windows), 
SPACE_RAISES_CONSOLE feature is implemented in wgraph.c

Key code is obtained in windows way.

*************************************************************

case WM_CHAR:
/* All 'normal' keys (letters, digits and the likes) end up
* here... */
#ifndef DISABLE_SPACE_RAISES_CONSOLE
if (wParam == VK_SPACE) {
WinRaiseConsole();
return 0L;
}
*************************************************************

WinRaiseConsole() is described in winmain.c





*************************************************************

void
WinRaiseConsole(void)
{
HWND console = NULL;
#ifndef WGP_CONSOLE
console = textwin.hWndParent;
#else
console = GetConsoleWindow();
#endif
if (console != NULL) {
ShowWindow(console, SW_SHOWNORMAL);
BringWindowToTop(console);
}
}
*************************************************************




In wxt terminal on windows (wxt_gui.cpp), key code scan seems to be wrapped by 
event.GetKeyCode()

Using the keycode
*************************************************************
switch (keycode) {


#ifndef DISABLE_SPACE_RAISES_CONSOLE
case WXK_SPACE :
if ((wxt_ctrl==yes && event.ControlDown())
|| wxt_ctrl!=yes) {
RaiseConsoleWindow();
return;
} else {
gp_keycode = ' ';
break;
}
#endif /* DISABLE_SPACE_RAISES_CONSOLE */
*************************************************************
Function RaiseConsoleWindow() is described in winmain.c



wxtPanel::RaiseConsoleWindow() is described dependent on platform,


The wxt terminal for windows uses  WinRaiseConsole() in winmain.c.

For windows terminal it should be required to write wrapper function to keycode to implement the Ethan's idea.
