How to play F♯dim on ukulele

Shape 1, 2-0-2-0, reading from the G string on the left:

A: index finger, 2nd fret of the G string.
F♯: middle finger, 2nd fret of the E string.
Leave the C and A strings open: C and A.

If an open string sounds dead, a fingertip is leaning on it. Come down more on the tips, with your knuckles bent.
Strum with the pad of your index finger or thumb, all four strings, across the spot where the neck meets the body.
