Mod5 is mapped for AltGr on Linux. And it should also be passed to the XIM,
like NumLock. So, it should be OK to add Mod5Mask to the list as well.
However, is this assumption reliable? In summary, the masks that should
be passed to the sequence checking routine are Shift, CapsLock, NumLock,
and AltGr. And the known mappings are:
bin. Macro Linux AIX Operation
---- ----------- --------- -------- ---------
0x01 ShiftMask Shift Shift Pass
0x02 LockMask CapsLock CapsLock Pass
0x04 ControlMask Ctrl Ctrl Block
0x08 Mod1Mask Alt Alt(?) Block
0x10 Mod2Mask NumLock ? Pass(?)
0x20 Mod3Mask ? ? ?
0x40 Mod4Mask Win ? Block(?)
0x80 Mod5Mask AltGr NumLock Pass
Or is there more reliable way to handle this?
