I'd like to be able to select columns (vertically). I've seen this in one of Microsoft's Visual Studio editors (version 6 if I recall) and it is incredibly useful. Holding down a modifier key like shift, control or alt and dragging a rectangle across multiple lines should select columns (ie. cols 3, 4 & 5 across several full-length lines) which can then be cut/copy/pasted across multiple columns, inserting the text into the middle of multiple lines. This is very useful for HTML as well as programming code, allowing a developer to paste a list of variables or parameters into several lines of similar code.

Is there a way to do this already or to have someone implement this functionality in jEdit?
