Sounds like you may be using a bluetooth or laptop keyboard. Hold the function key while pressing F4.
You can also acces the text parameters by selecting the text layer in the layer list, then going to the Inspector and selecting the Text Tab. Behaviors can be added multiple ways.
-From the Library with the Apply button.
-By dragging the behavior from the library onto the layer in the layer list, timeline or in the canvas.
-From the Behaviors button in the tool bar.
Make sure you select the text layer first and then use one of the methods above.
