How do I display a memory map of my variables and their addresses?
I am looking through the .map file but I cannot see a final memory map of all the variables. Is there a way to do this with Keil?

Note that you won't get automatic variables in the linker map...
Thanks, I had missed that auto variables would not appear, doh!
I am just starting with the ARM (STM32F4). I am doing some basic testing like cheking the speed of interrupts.
I had some variables declared as volatile in an interrupt routine and assumed they would then be global and I could see them. Re-declaring them as static showed them in the memory map. Changing them from automatic to static atually had a detremental impact on the speed.

No - volatile has nothing to do with scope or lifetime!
"Re-declaring them as static showed them in the memory map. Changing them from automatic to static atually had a detremental impact on the speed"
When they were automatic, they might have been in registers?
But did you actually want them to be global...?
How to see variable address in keil. And is it possible to change variable value directly from memory.
