Selecting and Moving Markers
How to select one marker or many in ZeroCount, move and resize them on the drawing, delete them, and work with detection thumbnails in the sidebar.
Marker Menus
The three menus you use on individual markers in ZeroCount: the floating action menu beside a selected marker, the overlap picker for stacked markers, and the right-click menu on a sidebar thumbnail.
Managing Groups
How to read a marker group row in ZeroCount and use its menu: renaming, adding markers, duplicating, deleting, collapsing, the merged-templates badge and the active service pill.
Merging Groups
How to combine two marker groups in ZeroCount, which one survives, what happens to the symbol templates, and how to repeat the same merge on every other drawing in the project.
Group Appearance
How to change a marker group's colour, opacity and border width in ZeroCount, what each slider does for each marker type, and the preference that sets the default border width.
Group Visibility
How to hide or cover marker groups in ZeroCount without changing what has been counted: the per-group Cover and Hide options, the sidebar type filter, and Cover All and Hide All.
Group Notes
How to leave notes on a marker group in ZeroCount, so queries, assumptions and decisions stay attached to the takeoff instead of living in your inbox.

Annotation Markers
How to add shapes, arrows, lines, text and images to a drawing in ZeroCount, where the annotation tools live, and why annotations never affect a count or the Excel export.
The Live Legend
The Live Legend in ZeroCount draws a key of everything counted on the drawing and keeps it up to date as you work. How to add one, switch its view and refresh it.
