Thanks for your suggestion. This request has been added to https://winscp.net/tracker/701

In newer versions if windows, there is a nifty power-user trick when mass-renaming files. It would be useful if this trick was in WinSCP.

The trick is that when you rename a file in windows, instead of pressing enter to confirm you can press TAB to rename and then switch the focus of renaming to the next item in the list. This is extremely useful when mass-renaming files, like I said before.

Thanks
