How do I get commands to show in stock recovery

[two_cents]

I have a stock update zip for 6.0 and I'm trying to flash from stock recovery... I get thru bootloader into recovery but no commands show up... Just the android with the red exclamation point on a black screen... Is there a button combination I need to hold to show commands for flashing the update zip? I've tried most of them I can think of for 5 seconds any that involve the power button turn off the phone
