How do I make and's together with or's?

I need some help with my game.

I want to implement this to my game:

when pressing Shift

or

When touching A

and

Player is on the floor

set

platform max speed to 275

Is this possible?

To make the "Player is on the floor" condition for Shift and A conditions .

Thanks

My game:

scirra.com/arcade/adventure-games/nick-28314

Move "Player is on the floor" to a sub-event.

when pressing Shift
or
When touching A
     Player is on the floor -> set platform max speed to 275
