What does 만지작거리다 mean?

만지다 means "to touch" or "to feel," but 만지작거리다 means "to finger with," "to fiddle with," "to fumble with," "to tinker with," and "to paw."

I came across the word while looking at the following Chinese character:

• 弄(롱) tease; play

Here is how the character is described in Naver's Chinese character dictionary:

王(왕☞玉)과 이외의 글자 공(양손)의 합자(合字). 손에 구슬을 가지고 만지작 거린다는 뜻

Notice that the description uses 만지작거리다 to say the character represents "a hand holding and fingering gems (or beads)."
