This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 抾 is uncertain. It visually combines 扌 (hand) with 去, but the original semantic and phonetic roles are unclear.
The hand radical 扌 beside 去 suggests an action of removing or taking away, but the exact meaning is not preserved.
For キョ, imagine a hand (扌) going (去) to take something away with a quick 'kyo' sound: kyo -> キョ.
