Possible patch to fix the bug

In some cases it was not possible to write latvian accented characters. For example, when saving html pages from Firefox, it was not possible to enter accented characters in filename, or to make a new folder (from Firefox save menu) with accented Latvian characters. It was also not possible to enter accented characters in Inkscape. Combinations like Ctrl+Alt+F1 was not working, eather.

Solution (a very simple one). Problem was with RALT modifier key. I replaced this with include from level3 file:
include "level3(ralt_switch)"

This part of file gets included:
default partial modifier_keys
xkb_symbols "ralt_switch" {
  key <RALT> {
    type[Group1]="ONE_LEVEL",
    symbols[Group1] = [ ISO_Level3_Shift ]
    };
  modifier_map Mod5   { ISO_Level3_Shift };
};

After the fix it is possible to enter latvian accented characters also in Inkscape and all other mentioned places, combinations like Ctrl+Alt+F1 are working as well.
