# SECTION: default
*font*
Font and style to use, in fontconfig format. See *FONT
FORMAT*. Default: _monospace_.
Comma separated list of fonts to use, in fontconfig format (see
*FONT FORMAT*).
The first font is the primary font. The remaining fonts are
fallback fonts that will be used whenever a glyph cannot be found
in the primary font.
The fallback fonts are searched in the order they appear. If a
glyph cannot be found in any of the fallback fonts, the dynamic
fallback list from fontconfig (for the primary font) is
searched.
Default: _monospace_.
*geometry*
Initial window width and height, on the form _WIDTHxHEIGHT_.
