 Although \texttt{forest} will arrange the nodes in the tree for you, you can still adjust both the horizontal and the vertical spacing, and the empty space around the nodes. The horizontal spacing is controlled by the \texttt{s sep} command, the vertical (or level) spacing by the \texttt{l} command. The \texttt{inner sep} command controls the empty space around the nodes. 
 
-You can specify absolute values for these parameters, as in the example below, or increase or decrease their default values as calculated by \texttt{forest}. This is done either by multiplication (e.g. \texttt{l*=3} multiplies the default by 3), or by addition or subtraction (e.g. \texttt{l+=3mm} adds 3mm to the default, \texttt{l-=3mm} subtracts 3mm).

-Arrows are drawn using the \verb|\draw| command. This command takes two arguments, which specify the source and the target of the movement, respectively. The source and the target are defined by giving a name to the relevant nodes in the tree with the \texttt{name} command. In the example below, the target is named \texttt{tgt}, and the source \texttt{src}. The \verb|\draw| command tells \texttt{forest} to draw a line from \texttt{src} to \texttt{tgt}. Place the command following the final closing bracket of your tree.

 The optional argument of \texttt{draw} is used to specify the placement of the arrow (up \texttt{[->]}, or down \texttt{[<-]}, both \texttt{[<->]}, or none \texttt{[-]}), and the line style (e.g. \texttt{dotted}). You can also specify where exactly at the source and target nodes the line should start and end by specifying this as an option with the \texttt{to} command; this is done using the option setting \texttt{south} for the bottom of the node, \texttt{north} for the top, \texttt{south west} for bottom left, etc.

The default is that the annotation will be placed on the line, so you will probably want to shift it a bit to the left or right to put it beside the line.
