This is a follow up on my earlier post regarding copying object while retaining horizontal or vertical alignment.
I just figured that the easiest way to do this is to: 1) Copy object 2) Paste in place (from the edit menu) 3) then move the new object while holding the ctrl key
It is quite interesting to compare the xfig and inkscape interface. Although Inkscape is nowadays 100x better than xfig, the original xfig interface has some nice features with which you can do some things really quick (Maybe that is just because I am used to it. But to give just an example). For example, if you have a drawing and there is a whole bunch of objects that need to be copied, each to different place. In Xfig, you can just click the copy icon, and you are in copy mode. Every object you touch with your mouse+click will be copied. In Inkscape, or any other modern drawing program for that matter, you need to perform a couple of operation to each object. I wonder whether I am the only one whole likes these Xfig features.
