For easy display of a node's multiple inputs and outputs in the Player, you can cycle the inputs or outputs shown by the Player using hotkeys. When in tool input mode in the Player, pressing the 5 hotkey a second time cycles to the next image input. Once the last input is reached, pressing the 5 hotkey again cycles back to the first image input. When in tool output mode in the Player, pressing the 6 hotkey a second time cycles to the next image output. once the last output is reached, pressing the 6 hotkey again cycles back to the first image output.
For added flexibility, you can assign a context point to a tool node. For example, while viewing the output of a tool in one Player, you may also want to view the result of a composition, matte, or other Keyer super tool output in another Player. To do this, add a context point (C1, C2, C3 or C4) to the Keyer super tool and assign a Player view to that context point. Then, use the context point's hotkey number (1, 2, 3 or 4) to cycle through the Keyer's outputs. See Setting Context Points.
