No key event for 2 keys

[thyresias]

I'm using a 105-keys keyboard, similar to this one:
http://en.wikipedia.org/wiki/File:Cherry_keyboard_105_keys.jpg

Two keys are not "seen" by ST (no key event reported, only chr event):

• the one to the right of the left shift (labeled < > on the picture)
• the one to the left of the right shift (labeled _ - on the picture).

CheckScanCode reports respectively:

• virtual code 226 / scan code 5636096
• virtual code 223 / scan code 3473408.

Are there names for these keys, so we can bind them with modifiers (ctrl etc.)?

A little up on this question.
Is there a better place to ask such questions/reports bugs?
