title: Selecting lines with different lengths in visual block mode
body: <p>I want to select a code block that consist of lines of different lengths in  visual block mode. However, since the cursor can only go as far as the end of each line, it's impossible to select the whole block of code shown below at once. Is there any tip for doing this?</p>
