Rebuilding

Mnemo is being rebuilt, so downloads are paused while we finish the new desktop app. We are moving Mnemo to a new interface and rebuilding every screen. Some screenshots on the site still show the current app while the new version takes shape.

Editing the canvas

Outliner keys, the tool dock, cross-links, and the radial menu.

The canvas is where a map is built. The fastest way through it is the keyboard; the dock along the bottom is for what has to be placed by eye.

Tab and Enter grow the map

Select a node and press Tab. A child appears, already selected, with its label open for typing. Enter does the same sideways: a sibling under the same parent. Shift+Tab lifts a node out from under its parent and drops it beside it; a node directly below a root cannot outdent.

The smaller moves:

KeyWhat it does
F2Edits the selected node's label, or a selected edge's.
Ctrl+DDuplicates the selection (Cmd+D on macOS).
DeleteRemoves it. Backspace does the same.
Ctrl+0Fits the whole map in the pane.
EscapeCancels the gesture in flight, then disarms the tool.

Dragging a node carries its whole subtree, and dragging a frame carries its members.

The tool dock

ToolKeyWhat a press on the canvas does
SelectVSelects, drags, and resizes. The resting state.
NodeNPlants a node and opens it for typing.
ShapeSPlants the shape chosen in the picker.
TextTPlants a loose text label.
ConnectCDraws an edge between two nodes.
FrameFSweeps a rectangle to frame what it catches.

Every tool but Select is one-shot: it does its one thing and hands the map back. The shape tool opens a picker of eight primitives.

Arm connect, press on a node, drag to another, and release. Mnemo draws the edge and returns to Select, and F2 labels it. Dragging between two nodes that are already linked removes that edge instead.

The radial toolkit

Hold Q, flick the pointer in a direction, and let go: the release runs the sector under the pointer. Letting go over the hub calls the gesture off, and Escape closes it. With a node selected the ring offers add child, connect, delete, add sibling, collapse, and edit; with nothing selected, add node, shape, arrange, fit, and add text.

Every key on this page is rebindable in Settings.
