If the \cw{BoldAsColour} resource is set to 1 (the default), bold
text will be displayed in different colours instead of a different
font, so this option will be ignored. If \cw{BoldAsColour} is set to
-0 and you do not specify a bold font, \cw{putty} will overprint the

\dt \cw{\-fw} \e{font-name}
