Chrome's custom search engines, like Firefox's keyword bookmarks, are great at getting information with fewer key taps. One Lifehacker reader recommends creating a search that auto-fills your home address into Google Maps for easy, quick directions to any destination.
huh989 gives the details on creating a custom search engine with your address auto-filled in the first field in Maps' directions. Right-click on your address bar, choose "Edit search engines", then click the "Add" button. Then fill in something like this:
Name: maps.home Keyword: maps.home URL: http://maps.google.com/maps?f=q&source=s_q&hl=en&q=from+cn+tower+toronto+ontario+to+%s
(Change the address in the url to your own obviously, separating the spaces with +'s)
huh989 is using "maps.home" as the text you have to type in first, perhaps because of other search engines he's set up, but I went with the more simple "goto" as my keyword. Either way, you can type in your keyword, then simply enter the address or place you want directions to. The extract click or copy/paste you save adds up over time.
