Only way to interface with buttons etc would be to use another macro that specificially clicks on an x,y location of the screen that is executable from the command prompt by which a batch file could use the start command to trigger the button command.
I think the OP was referring to buttons pressed on the keyboard.
For example Alt+Enter.
If that's the case. It only works in vbscript. Here is how you could do it.
Copy and paste into notepad and save as .vbs
Set ws = CreateObject("WScript.Shell")
ws.SendKeys "%{ENTER}"
Set ws = Nothing
Now you call it from a batch file:
@echo off
wscript /nologo whatever.vbs
If you are trying to send ALT + ENTER to the command prompt in order to full screen it, it won't work. It's a Microsoft bug. It will work for any other program though. If you need to maximize the command prompt inside batch, there is a way. Just post back if that's what you are trying to do.
