FreeMind (an open-source mindmapping tool) has some handy features, which may also improve your productivity:
- Shortcuts: Use the shortcuts like ENTER and INSERT and navigate via the ARROW keys!
- Creating subnodes from your clipboard: If there are several lines of text in the clipboard and you paste its content into FreeMind while a node is selected, then several subnodes will be created. That is really cool and i discovered it by accident!
FreeMind can be downloaded from http://freemind.sourceforge.net/
