Auto-Throttle Arm switch for Embraer E-jets Pack

I am not able to find the switch and cannot set speed control in autopilot. Any help would be appreciated.

See if this helps.

Z = toggles autopilot on or off
Ctrl+Z = holds your current altitude
Ctrl + H = holds your current heading
Ctrl + N = holds your navigation instrument (whether it's a navigation radio or a GPS course)

Thanks RadarMan. The autopilot switches also control those settings, however the "speed" hold does not work without the auto-throttle being armed.

Hope this does it.
