Visual-Block Mode

The last of Vim's visual modes is called visual-block mode, and is demonstrated using the following buffer:

Enter visual-block mode by pressing C-V:

Finally, move the cursor to another location in the buffer.

The key observations are:

1. The selection starts from the upper-most cursor location (the cursor location when the editor entered visual mode),

2. The selection ends at the lower-most cursor location (the current cursor location),

3. The selected content contains text that exists between the start and end of the selection, but only from columns that are also between the starting and ending cursor locations.
