# This will map:
# <Win> + Left to Home
# <Win> + Right to End
# <Win> + Up to Page Up
# <Win> + Down to Page Down

# Modify /usr/share/X11/xkb/symbols/pc, replace the definition of <LEFT>, <RGHT>, <UP> and <DOWN>
    key <LEFT> {
        type[Group1]= "PC_SUPER_LEVEL2",
        symbols[Group1]= [ Left, Home ]
    };
    key <RGHT> {
        type= "PC_SUPER_LEVEL2",
        symbols[Group1]= [ Right, End ]
    };
    key <UP> {
        type= "PC_SUPER_LEVEL2",
        symbols[Group1]= [ Up, Prior ]
    };
    key <DOWN> {
        type= "PC_SUPER_LEVEL2",
        symbols[Group1]= [ Down, Next ]
    };

# Note: GNOME settings related to Super + Arrow need to be removed for this to work

# HACK: We also need to patch libX11 for this to work properly in Chrome
# Edit src/XlibInt.c
# In _XWireToEvent in KeyRelease, add the following at the end of the case (after ev->kekeycode)

#define REMAP(from, to) if (ev->keycode == from && ev->state & 0x40) {ev->state = ev->state & ~0x40;ev->keycode=to;}
REMAP(114, 115);
REMAP(113, 110);
REMAP(111, 112);
REMAP(116, 117);
