In the rulebook page 32 "timing structure of turns"

Number 1. Corporations draw phase ( color blue)

I read that it starts with a green arrow which stands for " paid abilities can be triggered" number 1.1

My question: in this step number 1, substep 1.1 can only the corporation make use of this paid abilities or also the runner?

Or has the runner to wait till the "the runners action phase" (color purple)?

Thanks in advance

May I draw your attention to page 21:

Timing Priority

Whenever there is an opportunity to trigger paid abilities, rez cards and/or score agendas (usually at the beginning of a turn and after each action), the player who is currently taking his turn gets the first opportunity to act. He can trigger as many abilities, rez as many cards, and/or score as many agendas as he wishes in the order of his choosing. When he is finished, the other player gets the opportunity to act. When that player is finished, the first player gets the opportunity to act once again.

Thank you

So the answer is everytime, starting with the player whose turn it is.

Thanks
