Thanks, but ${} did not work in the workflow to rename an output file. 
It takes ${} to be a user provided parameter.

${} will definitely work in tool definitions, but that means I have to 
change ALL the default tool names for all the tool in galaxy...Surely there 
must be a way to rename an output file to the original input file in the 
workflow step "Rename Dataset"?
