142 Formerly, we used PointerMotionHintMask (in standard_event_mask)
143 so that we would have to call XQueryPointer after each MotionNotify
144 event to ask for another such event. However, this made mouse tracking
145 slow, and there was a bug that made it eventually stop.
147 Simply asking for MotionNotify all the time seems to work better.
149 In order to avoid asking for motion events and then throwing most
150 of them away or busy-polling the server for mouse positions, we ask
151 the server for pointer motion hints. This means that we get only
152 one event per group of mouse movements. "Groups" are delimited by
153 other kinds of events (focus changes and button clicks, for
154 example), or by XQueryPointer calls; when one of these happens, we
155 get another MotionNotify event the next time the mouse moves. This
156 is at least as efficient as getting motion events when mouse
157 tracking is on, and I suspect only negligibly worse when tracking

9476 - Fn-Shift-j is regonized as Fn-j and not Fn-J.
9477 The above table always translates to lower characters. We need to use
9478 the KCHR keyboard resource (KeyTranslate() ) to map k->K and 8->*.
9480 - The table is meant for English language keyboards, and it will work
9481 for many others with the exception of key combinations like Fn-ö on
9482 a German keyboard, which is currently mapped to Fn-;.
9483 How to solve this without keeping separate tables for all keyboards
9484 around? KeyTranslate isn't of much help here, as it only takes a 16-bit
9485 value for keycode with the modifiers in he high byte, i.e. no room for the
9486 Fn modifier. That's why we need the table.
