Record Finger Pointer in "Karaoke Style"

Press the "..." button in the PDF document display.

Then select "Scroll / Finger Pointer."

Select "Record Finger Pointer."

Confirm and start the recording with this button.

Point with your finger where you want to see a red dot during playback later.

Press the "Stop" button to end the recording.

In the settings, you can define a small offset between your finger and the red dot so you can see the dot while recording.

Recording the position syllable by syllable can be difficult with fast songs. However, often it is sufficient to just display the current line with the dot.
