Note: Blinky is now part of Type – a powerful toolset for working with text layers in After Effects.
Blinky is an After Effects script that allows you to add a blinking cursor to any text layer in After Effects with one click.
Open the Blinky UI panel (Window > Blinky).
Select a text layer and click the Add Blinky button.
You should now have a new layer called [text-name]_cursor. If not, undo and try again (this is a known bug).
With the cursor layer selected, you can make the following adjustments to the cursor appearance.
Changes the color of the cursor.
When turned on, it round the ends of the cursor.
Sets the width of the cursor in pixels.
Sets the height of the cursor in relation to the font size of the text.
Sets the length of the blinking animation in frames.
