Google Drive is great for quickly finding your documents. The search function will find almost anything in a matter of seconds (even if hidden deep inside documents, pdf and image files) and you can star frequently used documents.
However,  there is even a faster way to your documents than staring them. By using Chrome bookmarks you can access your files without having to go into your Drive in the first place. I do this typically with files I use almost on a daily basis, like my lesson planner (a doc)  and my gradebooks (Google spreadsheets). All I need to do is star the document in the omnibox and then I can use autocomplete  to get to them quickly, e.g. “less..:” for lesson planner, or the grade for which I need the gradebook.  
You can even create new documents this way. However you will need to create the link manually in your bookmarks: 
- Go to chrome://bookmarks/
 - create a new bookmark to
 - https://docs.google.com/document/create
 - name it “new doc” (or anything you will remember, like “create document”)
 - and then you will be able to use the bookmark either from the omnibox, the bookmarks bar or the bookmarks page.
 
If you want to create shortcuts for a new slide or sheet, you only need to substitute the “document” part of the link with “presentation” and “spreadsheets” respectively.
