Default horizontal gap between keys.
May be a dimension value, which is a floating point number appended with a unit such as "
14.5sp
".
Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size),
in (inches), mm (millimeters).
May be a fractional value, which is a floating point number appended with either % or %p, such as "
14.5%

The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to
some parent container.
