http://vim.wikia.com/wiki/Inserting_text_in_multiple_lines

• On a character in the first line, press Ctrl-V (or Ctrl-Q if Ctrl-V is paste).
• Press jj to extend the visual block over three lines.
• Press $ to extend the visual block to the end of each line.
• Press A then space then Ctrl-R then + then Esc.

Get name of the current file

Register % contains the name of the current file, and register # contains the name of the alternate file. These registers allow the name of the current or alternate files to be displayed or inserted. The name, or full path, or directory containing the file can be used.

For example, in directory /abc the command vim def/my.txt would edit file /abc/def/my.txt. The following commands could be entered to display the information shown.

  :echo @%    def/my.txt  directory/name of file

Pyflakes

https://github.com/kevinw/pyflakes-vim

cd ~/.vim/bundle
git clone git://github.com/kevinw/pyflakes-vim

via http://mirnazim.org/writings/vim-plugins-i-use/

pyflakes-vim uses the output from PyFlakes to highlight errors in your code. To locate errors quickly, use quickfix commands like :cc :cw.

There was a bug that said 'Module' object has no attribute 'getChildNodes' It is reported in the issue:

https://github.com/kevinw/pyflakes-vim/issues/27

You can recommend to users that they clone the pyflakes-vim repo with git clone --recursive or you can suggest after the fact to use git submodule update --init --recursive if pyflakes-vim is saved as a git submodule itself.
