This may help just a little
If it is a chat function, the command is /messageSent "message"
commandToServer('messagesent',getClipBoard()); Nvm crown beat me to it lol
That way you can send something with more characters
But you will need to make silent eval functions (Pretty bad to do if you don't have any idea what you are doing) if whatever you are trying to eval is too big, such as uploading a code (basically a file), uploading big functions, etc.
