# uncomment the correct keyboard:

# The value of KBDFLAGS should be or'ed together from the following
# bits, depending on which features you want enabled.
# 0x80 - Off: the Alt key will set bit 7 if pressed together with
#             another key.
#        On:  the Alt key will NOT set the high bit; an escape
#             character is prepended instead.
# The least significant bits control if the following keys are "dead".
# The key is dead by default if the bit is on.
# 0x01 - backquote (`)
# 0x02 - accent acute
# 0x04 - circumflex (^)
# 0x08 - tilde (~)
# 0x10 - dieresis (umlaut)
