Vim Screencast: Selections
This is a relatively short screencast on a few different ways to select text in Vim. Vim's visual mode is a very powerful feature of the editor which allows you to select data in different, yet meaningful, ways.
The screencast goes over normal visual mode, visual block mode, and text object selection. The relevant helpfiles are::
:h visual-mode :h v_b_i :h text-objects
As a developer, its as important to know your editor as well as a carpenter knows his hammer. You can find this video at http://showmedo.com/videotutorials/video?name%3D3160010 (likely dead).
