OSX key layout - multiple modifier keys

[rasmuset]

Hi, 

I'm reworking the danish key layout to work on OSX for the most common / useful special chars. I'm testing with following written in the ducky script: 

| * @ ' " & / \ {} () [] = + - _ # : , .

I get the following output: 

| * @ ' " & / ¶ ¶≠ () [ = + - _ # : , .

So I have a few errors I'm trying to iron out.

Right now I got the following errors

] - gives me the error "Char not found:ASCII_5D", which is a little weird because it's set to ASCII_5D = KEY_9, MODIFIERKEY_RIGHT_ALT

\ - yields ¶, which seems to be because only one modifier key is allowed. On the danish layout the correct combination is ASCII_5C = KEY_7, MODIFIERKEY_RIGHT_ALT, MODIFIERKEY_SHIFT but the MODIFIERKEY_SHIFT is ignored. 

{} - yields [ and ], respectively and it this seems to be because of the same issue as with the backslash where the one modifier key is ignored. 

I'm having trouble figuring out how to set two modifier keys, if it's even possible, or find another way to map the keys. If anyone nows a way around this, it would much appreciated.
