Use the Guidelines tool to add snappable guidelines anywhere on your screen.
To add a snappable guideline, hold the left mouse button & drag in the direction of the object to which you want to attach it. When you're near the edge of the object release the left mouse button and the guideline will automatically snap to the object's edge.
In case you want to add a guideline to the exact position of your mouse cursor, use the available options from the context menu or the appropriate shortcuts from the list below.
