Oops, then I've something misunderstood.  I've read in Xkb doc, that:

"...all Xkb keyboard status events are reported to all interested clients,
regardless of which window currently has the keyboard focus and
regardless of the grab state of the keyboard."

I was happy because this is what I need.

XSelectInput() with KeyPressMask and KeyReleaseMask are out of
my interest because they lack if any other client grabs the keyboard.

Is Xi2 able to deliver me key events when an XGrabKeyboard() by a
different client is in effect?
