ketstroke question

Hi - My question relates to the 737 series keystroke commands.I am using the CP Flight MCP and EFIS and have altered many of the keystroke commands to suit this equipment (as suggested by CP Flight).Number 53 - MCP set TOGA; &Number 54 - MCP resetr TOGAI understand what they mean, but should I have them mapped to the MCP or leave them as is? These two settings are not mentinoed in the CPFlight tutorial on MCP set up.I hope there is another CP Flight MCP user out there reading this. Thanks....IAIN
