When pressing AltGr on my (not Dell) keyboard, xev returns:

~~~
KeyRelease event, serial 48, synthetic NO, window 0x2800001,
    root 0x528, subw 0x2800002, time 37381333, (41,47), root:(792,492),
    state 0x90, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen
YES, XKeysymToKeycode returns keycode: 92
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False
~~~


So... ISO_Level3_Shift also seems to be synonymous with AltGr...
