None. The window itself doesn't deal with the keyboard focus.
(Usually - it *may* request to receive the FocusIn and FocusOut
events, to do something itself). If the window has the keyboard
focus X sends keyboard events to its application (if requested),
if it doesn't have the focus it doesn't send them.
What are you trying to do in events.c? There is no check for
the pressed modifier key in the relevant part of the code:
-----------------------------------------------------------------------
void HandleButtonPress(void)
{
int LocalContext;
char *action;
Window OldPressedW;
DBUG("HandleButtonPress","Routine Entered");
/* click to focus stuff goes here */
if((Tmp_win)&&(HAS_CLICK_FOCUS(Tmp_win))&&(Tmp_win != Scr.Ungrabbed))
{
SetFocus(Tmp_win->w,Tmp_win,1); <---- !!!
...
-----------------------------------------------------------------------
The 'SetFocus' function handles focus switching. This works regardless
of the modifier keys held.
