Since: nightly builds only
If specified, overrides the position of underlines.
The default is to use the underline position metric specified by the designer of the primary font.
This config option accepts different units that have slightly different interpretations:
"2px"all specify a position of 2 pixels
"2pt"specifies a position of 2 points, which scales according to the DPI of the window
"200%"takes the font-specified
underline_positionand multiplies it by 2
"0.1cell"takes the cell height, scales it by
0.1and uses that as the position
Note that the
underline_position is often a small negative number like
-4 and specifies an offset from the baseline of the font.
