|WOW!... I gotta say you sound like you are being really short with someone offering up help. Harsh.|
I hope the help I'm offering doesn't initiate a similar response.
OK. I played with the gadget and here's what I got.
Do away with the codes (albeit for the meantime)
Hover the mouse pointer over the gadget and click on the wrench/spanner.
In the screen that pops up put a check-mark in "Display company name in place of a symbol" and click "ok".
Now when you search you can put whatever wish in... i.e. Hang Seng, FTSE or even Mars Mining Industries if it takes your fancy.
You should then be able to accurately make your selection with the elusive code displayed on the left.
Incidently the code that showed on the left for Hang Seng using this method is $HSIX
