Hint Keys and Hint Modes

Some modes allow you to select nodes by entering their corresponding red characters. These characters are called "Hint Keys" and modes that use hint keys to select nodes are called "Hint Modes". The characters h, l, and k always refer to the left node, right node, and parent node of the currently selected node, respectively.

In Travel Mode:

• press hint keys to travel to corresponding node

In MakeChild Mode:

• press hint keys to create a child of the corresponding node

In Delete Mode:

• press hint keys to delete the corresponding node

In Cut Mode:

• press hint keys to select a node to cut
