Quickmarks for Google Chrome makes bookmark keyword launching easy
Quickmarks is up to the task. Simply install the extension, and then do some manual editing. Any bookmark that you'd like to launch via a keyword needs to have [keyword] appended to its name. For example, you can right click your Gmail bookmark and choose edit, change its name to Gmail [gm], and Quickmarks is now able to launch it.
To open a bookmark using its keyword, simply click into the Omnibar or tap Ctrl+L B [space] and then enter your keyword. The B trigger tells the Quickmarks entension to fire up and watch for keyword input.
Since Chrome can sync both your extensions and your bookmarks, once your [keywords] are sent to the cloud you'll have access to them on all your Chrome installs.
