Hi,
Well, I tried the example for prefixing line by column and basically after several tries couldn't get it to work. I don't think I could select the 0 length column.
You can do it, either with the mouse or just the keyboard.
Using the keyboard to prefix three lines: --------------------------------------------------
Move the caret to the beginning of a line. Hold shift and press down arrow twice. Hit option once (to toggle between "normal" and "column" select).
You now have a 0-length selection at the start of the line that spans three lines.
Note that doing it in this way added a +1 line of column select -- something you'll have to remember is all.
Using the mouse to prefix three lines: -----------------------------------------------
Hold option down. Move the mouse to the beginning of the first line you want to prefix. Click and drag *straight* down to cross the three lines (don't pull the mouse right to make a box). Let go of mouse. Let go of option.
--> zero-width column select at the start of the three lines.
Just start typing and see.
I wonder how much work would be involved to write a bundle that offered this functionality. I suspect too much or some one would have done it already.
It's not that, it's just not necessary, really.
Give it another go :-)
