mode switch key mapping problem

I searched a lot of wikis, forums but i didn't find out how to configure this.

I'm using the romanian keyboard layout, configured like this in xorg.conf:

Section "InputDevice"
    Identifier     "Keyboard0"
    Driver         "kbd"
    Option         "XkbLayout" "ro"
EndSection

Alt_R / Alt Gr is by default mapped to switch modes. I managed to make the left Win Key change modes, by making a ~/.Xmodmap:

keycode 115 = ISO_Level3_Shift

Now both Alt_R and the left WinKey switch modes. I want to remove the mode switch from the right Alt, because i need it for other applications.
I tried putting remove / clear keycode 113 in .Xmodmap but it didn't work.
Also, why is arch/linux(?) using "ISO_Level3_Shift" instead of Mode_switch?

this is my output from xev:
for left winkey:

KeyRelease event, serial 31, synthetic NO, window 0x2000001,
    root 0x155, subw 0x0, time 14283222, (43,85), root:(466,375),
    state 0x90, keycode 115 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
    XKeysymToKeycode returns keycode: 113
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

alt gr:

KeyPress event, serial 31, synthetic NO, window 0x2000001,
    root 0x155, subw 0x0, time 14283906, (43,85), root:(466,375),
    state 0x10, keycode 113 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

Re: mode switch key mapping problem

Solved it.

I tried to add Option "XKbOption" "compose:lwin" in xorg.conf but it didn't work.

Finally, I switched to US keyboard and defined the language specific characters using xmodmap. Could have done this in the first place but i thought there was a way to remove the Mode_switch from Alt Gr. It would have been more elegant.
