Finally a programmer's editor with a "Duplicate Line" function

Finally there's a programmer's text editor that supports the "Duplicate Line" command. This is great, since I've been waiting for this feature since I stopped using SemWare's legendary QEdit in DOS (I can still remember the F4 key, which was the one to duplicate the current line). You could still use QEdit under Windows, but I prefer a GUI instead nowadays:

The editor that supports the Duplicate Line is UltraEdit from IDM Computer Solutions. This is a lucky thing, since UltraEdit also happens to be my favorite text/hex editor. I've so far been using version 10.20, but the newest 12.10 version support also code folding, multiple clipboards and Unicode, which are all features I've been waiting to see. It is time for an upgrade. For only $40, that's well spent dollars.
