# APPENDIX: STRING ESCAPES (make extracts from screen (1))
#
# The attribute set can either be specified as hexadecimal number
# or a combination of the following letters:
#
#   d     dim
#   u     underline
#   b     bold
#   r     reverse
#   s     standout
#   B     blinking
#
# Colors are coded either as a hexadecimal number or two letters specifying
# the desired background and foreground color (in that order).
# The following colors are known:
#
#   k     black
#   r     red
#   g     green
#   y     yellow
#   b     blue
#   m     magenta
#   c     cyan
#   w     white
#   d     default color
#   .     leave color unchanged
#
# The capitalized versions of the letter specify bright colors.
# You can also use the pseudo-color `i' to set just the brightness and leave the color unchanged.
