It's easy to make careless formatting mistakes if one directly types the entries in the reference list. With BibTeX, you can automatically generate those entries. Vim is the best editor, and Vim-LaTeX is even the more powerful, especially for writing equations. (See my previous video: http://www.youtube.com/watch?v=y67t-05nFD0)
This video shows only one keyboard shortcut for citing information on Vim-LaTeX:
In a .bib file on Latex-Suite, typing 'BBB' gives you some essential fields.
For more shortcuts (BBL,BBH,BBX), please see the official documentation. 
The biblatex-apa package, which, according to CTAN, requires the biber backend , is used due to the @online tag , and more.  As a result, the F9 key in Latex-Suite can't be used, but the Ctrl+n auto-completion still works.
