Tab on the map creates a child node when a node is selected; without a selection Tab moves focus. Enter opens details on a focused node, adds a sibling when a node is selected elsewhere, or creates an unattached task when nothing is selected. Space cycles task status when applicable. Arrow keys move between related nodes after one is focused. Alt 1 through Alt 4 set priority Critical through Low. Use Control F or slash to search nodes, Control A to select visible nodes, Control Z to undo, Control Y to redo, Control K for commands, Control D to duplicate, Control Enter to cycle status, F2 to rename in details, plus and minus to zoom, and zero to fit the map. Control click toggles multi-select; Escape closes panels and clears selection.
