How do I set two functions when I only have one button?

"On my D300 I use focus assigned to AF On and set AE-L/AF-L to AE Lock Hold. What do I do on my backup camera which only has one button? (AE-L/AF-L)"

Simple: set AE-L/AF-L to AF On and use Manual exposure mode. Exposure is locked until you change it ;~). Focus still only happens when you press a button.
