How can I display a coordinate grid in the map canvas?

Question

I want a live renderizing grid on the map canvas in QGIS, during processing, not on the map composer. Does anyone know how to do that?

Answer 1

'View > Decorations > Grid'. The Grid properties allows you to set line type and interval, as well as any annotations (such as lat/lon). This is purely an overlay that you can't interact with and doesn't render in the print composer.
