Explicação
Means B happened right after A, often unexpectedly. It describes something the speaker observed with surprise, or a sudden change; A and B are often opposites, as in crying and then laughing. It is not used for the speaker's own actions, and the second clause cannot express intention or a request.

Observações
Do not use it for your own actions. While か〜ないかのうちに stresses near-simultaneity, たかと思うと focuses on the sudden or surprising change after A.
