Waits until a key is pressed, then sets the border to white.

This is the same key wait as Normal_AnyKey, but it sets the border to white before returning.

| Turn_WaitForAKey | 969A | XOR A | Read from the keyboard port. | |
| 969B | IN A,($FE) | |||
| 969D | AND %00011111 | Keep bits 0-4, one for each key in the half-row. XOR A then IN A,(FE) reads every half-row at once, and a pressed key reads as a reset bit. | ||
| 969F | CP $1F | Loop back to Turn_WaitForAKey until any key has been pressed. | ||
| 96A1 | JR Z,Turn_WaitForAKey | |||
| 96A3 | LD A,$07 | Set the border to white. | ||
| 96A5 | OUT ($FE),A | |||
| 96A7 | RET | Return. | ||
