SendText.ps1

<#
 SEND Text just types out the text in the input to send over rdp where copy and paste is not enabled.

 1. put the text you want to send as the $input variable
 2. set timeout (optional) to the number of seconds you want to wait until it starts to send
 3. Start script
 4. before the timeout is complete, put the mouse focus on the window you want input the text to
        RDP -> Notepad on remote system
 5. Wait for the text to fully send.  Depending on how long the string is, it could take a while.

 Cool parts:
     You can use command keys (such as Enter, or DEL keys as well)

 Potential problems:
     Network issues could cause lost keystrokes over rdp.  verify the string was sent properly
     Really only works with standard US character keyboard set.  I tried it with chinese characters and the script failed.
