Quick Upload for Scripters

I mainly use SmartFTP when I'm writing CGI scripts, and the usual routine is to upload the recent version, test it, make modifications to the file, upload it again, test it, make modifications.... and so on. It would have been nice to be able to initiate the upload of that same file in a somewhat quicker manner. Right Click->Upload->Direct->Select Files->etc can become quite tedious if all you want to do is to upload that one file over and over again. Some hotkey or a simple button on the toolbar for uploading the last uploaded file would be nice.
