xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock
control     Control_L (0x25),  Control_L (0x42),  Control_R (0x69)
mod1        Alt_L (0x40),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3
mod4        slash (0x85),  Super_R (0x86),  slash (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

I ran `xmodmap .Xmodmap' with those lines added and then ran just
xmodmap, getting the above ouput.  This is identical to the output of
xmodmap I sent previously, without the added lines from you.  Do the
added lines need to be in a particular order with respect to the
existing lines?  Currently my .Xmodmap has these uncommented lines, in
the order listed:

remove Lock      = Caps_Lock
keysym Caps_Lock = Control_L
add    Control   = Control_L
remove mod4 = Super_R
remove mod4 = Hyper_L
remove mod4 = slash
keysym Super_L = slash
keysym Menu = backslash
