+ <strong>Background Dependent Text Colour</strong>
+ <p>
+ The <strong>Colour→Text Colour</strong> menu entry opens the <strong>"Adjust
+ Foreground Text Colour Threshold"</strong> dialog box, allowing the
+ colour of symbols rendered on dark or light backgrounds to be set
+ for the current selection or the whole alignment.
+ </p>

+ <p>The dialog box contains a slider, and two colour icons showing
+ the text colour for dark backgrounds (left hand end of slider), and
+ light backgrounds (right hand end of slider). Drag the slider to
+ change the threshold for transitioning between dark and light
+ background colours, and select either of the colour boxes to open a
+ colour chooser to select a different text colour.</p>
