Selecting nodes
You've been selecting nodes for a while now, but I never really explained this properly.
Well done for succeeding without detailed instructions.
• To select one node, click once in the center of the node.
• To select multiple nodes, click and drag around them to draw a marquee, or Shift-
click to select more than one node.
•Toselectallupstreamnodesfromanode,Ctrl/Cmd-clickthebottomnodeanddrag
a little. Upstream nodes mean all the nodes that go up from the current node. In
FIGURE 2.21 , notice that Merge1 isn't selected as it's not upstream from Blur1.
Figure 2.21. Holding Ctrl/Cmd and dragging to select all upstream nodes.
