Say I have a directory with one file in it mylongfilename.blahdeblah.txt now the keystrokes mv [tab] [tab] will result in mv mylongfilename.blahdeblah.txt mylongfilename.blahdeblah.txt on my command line
What I'd now like to do is type something in the place of the second blahdeblah If I hit ctrl-b a few times I'll be back at the . before .txt At this point I want to type something like ctrl-w to delete to the preceding . Ie I'd end up with mv mylongfilename.blahdeblah.txt mylongfilename..txt
Is there a keystroke similar to ctrl-w that will do that? (Ctrl-w will delete to the preceding space - not what I want)
