Question 1

What is a mind map and how do I create one?

Accepted Answer

A mind map is a visual brainstorming tool that organizes ideas hierarchically. Double-click empty canvas space to create a node. Use Tab to add a child node, Enter to add a sibling, and F2 or double-click to edit labels. Drag nodes to rearrange them, and scroll to zoom in or out.

Question 2

How do I navigate and search my mind map?

Accepted Answer

Drag empty canvas space to pan around. Use the scroll wheel to zoom (0.2x to 3x). On touch devices, pinch to zoom and double-tap to create nodes. Press Ctrl+F to open the search overlay and find nodes by text, with prev/next navigation and auto-centering.

Question 3

Can I undo changes?

Accepted Answer

Yes. Press Ctrl+Z to undo up to 60 steps. This covers node creation, deletion, label edits, and repositioning. If you accidentally delete a node (and its descendants), undo will restore the entire branch.

Question 4

How do I export my mind map?

Accepted Answer

Click the export buttons to download your map as a PNG image (mindmap.png) or a text outline (mindmap.txt). The text export uses #  for the root node and -  for children with indentation, making it easy to paste into a document or Markdown editor.

Question 5

Is my mind map saved?

Accepted Answer

Yes. Your map is auto-saved to your browser's localStorage every few seconds. If you close the tab and return later, your nodes will be restored. Like all ReadCalc tools, nothing is sent to any server — everything stays on your device.
