Show Invisible Characters in Vim

Once you get used to Python layout and Markdown, there are times you want Vim to visualize blank lines and tabs.

Show them temporarily in Vim

: set list
: set listchars=tab:»-,trail:-,eol:↲,extends:»,precedes:«,nbsp:%,space:_

Show them permanently

Add the following to ~/.vimrc

set list
set listchars=tab:»-,trail:-,eol:↲,extends:»,precedes:«,nbsp:%,space:_

Turn the display back off

Inside Vim,

:set nolist
