That is, bind the = command to a convenient key in your init.el and try remember to use it = while editing. Note where it works as desired and where not. Some of what I found: * Having the cursor remain in the same column is very useful as it's = usually near the spot to be edited in the original or copied line. = Automatically moving it to the beginning or end of the line would make = it worse. * Whether it is better to keep the cursor on the first line (as if = duplicating downwards) or the last line (as if duplicating upwards) is = less clear. It basically comes down to whether it is more common to want = a similar but different line above or below the original line. I weakly = favour the current design because it generalises better and it's = slightly more convenient to edit a sequence of lines top-down than = bottom-up. * A single-key binding (like H-y but not C-x y) makes quite a difference = because that way I can quickly stutter out copies as needed without = having to plan ahead and use prefix arguments. * Rectangle duplication is very useful when editing tables or code with = similar structure. Compared to copy-paste, it saves a lot of cursor = movement and permits immediate repetition if more than one copy is = required. I would be very interested in your own experience (much more than = anyone's theoretical speculation). > The benefit of adding the region sensitive behaviour seems even > slighter, and the problem is, as I said, that it subverts the > (currently) clear semantics the new command has. It's not an unnatural combination; several other editors have similar = commands. Moreover, even if you don't find the region-sensitive behaviour, others = do -- for rectangular regions in particular. Nobody is going to complain = that there are functions in Emacs that they don't care to use, = especially when they don't take up extra keybindings.
