working with range markers is a nice thing and makes several things easy to do.
At the moment I’m asking myself why/if there’s not a permanent rangeline
at the end of the range. Start of range marker has this line down to bottom (red line left),
end-of-range-marker not (see screenshot). Bug/feature/misunderstanding ?
If you want all markers & range starts & ends to have vertical lines, enable ‘Show Marker Lines’ from the ‘View’ menu.
The red line is the selected marker - click on any marker, or range start or end, to select it, and that line will appear regardless of the ‘Show Marker Lines’ setting.
