Just to be clear  you are wanting to launch a program from a batch file and then have the batch file press keys  in your example  the arrow keys  within that launched program   If that is the case  you aren t going to be able to do that with simply a   bat  file as the launched would stop the batch file from continuing until it terminated--   My first recommendation would be to use something like AutoHotkey or AutoIt if possible  simply because they both have active forums where you d find countless examples of people launching applications and sending key presses not to mention tools to simply  record  what you want to do  However you said this is a work computer and you may not be able to load a 3rd party program   but you aren t without options    You can use Windows Scripting Host from something like a  vbs file to launch a program and send keys to that process  If you re running a version of Windows that includes PowerShell 2 0  Windows XP with Service Pack 3  Windows Vista with Service Pack 1  Windows 7  etc   you can use Windows Scripting Host as a COM object from your PS script or use VB s Intereact class   The specifics of how to do it are outside the scope of this answer but you can find numerous examples using the methods I just described by searching on SO or Google   edit  Just to help you get started you can look here    Automate tasks with Windows Script Host s SendKeys method A useful thread about SendKeys

Wow  Mean this that you must learn a different programming language just to send two keys to the keyboard  There are simpler ways for you to achieve the same thing   -   The Batch file below is an example that start another program  cmd exe in this case   send a command to it and then send an Up Arrow key  that cause to recover the last executed command  The Batch file is simple enough to be understand with no problems  so you may modify it to fit your needs    if   CodeSection     Batch   then    echo off  rem Use  SendKeys  to send keys to the keyboard buffer set SendKeys CScript   nologo   E JScript    F0   rem Start the other program in the same Window start     B cmd   SendKeys   echo off ENTER    set  P   Wait and send a command     lt  NUL ping -n 5 -w 1 127 0 0 1  gt  NUL  SendKeys   echo Hello  world  ENTER    set  P   Wait and send an Up Arrow key      lt  NUL ping -n 5 -w 1 127 0 0 1  gt  NUL  SendKeys    UP    set  P     Wait and send an Enter key    lt  NUL ping -n 5 -w 1 127 0 0 1  gt  NUL  SendKeys    ENTER     SendKeys   exit ENTER    goto  EOF    end      JScript section  var WshShell   WScript CreateObject  WScript Shell    WshShell SendKeys WScript Arguments 0      For a list of key names for SendKeys  see   http   msdn microsoft com en-us library 8c6yea83 v vs 84  aspx  For example   LEFT ARROW     LEFT  RIGHT ARROW    RIGHT    For a further explanation of this solution  see  GnuWin32 openssl s client conn to WebSphere MQ server not closing at EOF  hangs
