Here are some useful Vi commands I've encountered.

:!python -m SimpleHTTPServer 8080 This lets you run Python commands without leaving Vi. Then you set up a server on your machine so you can see how the HTML file looks live. I used this for editing and previewing the Bootstrap templates.

:.,$d This deletes from where the cursor is through the rest of the document.

:q! Override quit; if the file has changed, this will prevent saving it.
