Mapping arrows in commutative diagrams
The 2019 Stack Overflow Developer Survey Results Are InDrawing mapsto arrow in TikZTikz for Commutative DiagramsPositioning arrows in commutative diagrams using TikZ-cd (or otherwise)?Writing labels crossing over other arrows in commutative diagramsNumbering commutative diagramsFlipping an Arrow in a Cubical Diagram and Crossing OverDouble arrows in commutative diagramsParallel arrows in commutative diagram in TikzCommutative diagrams with very round arrows?Drawing rectangular commutative diagramsCommutative diagrams and arrows
In making commutative diagrams in tikz-cd I've been wanting to add in 'mapping' arrows that describe what particular elements map to, parallel to the main diagram arrows.
I've been doing it in the following way, which seems fairly clumsy since the 'map' arrows are separated from the main diagram at a large distance, when ideally they would be close by and parallel to the corresponding maps. What would be a better way to do this?
