On top of using this tool to pick out random snippets of foreign language, it can save you 10’s… maybe 20’s (8/31/09 UPDATE: over exaggeration) of FireFox Extensions that, depending on which ones you have installed, may slow down your browsing experience. Creating tinyURLs, saving dates to Google Calendar, and easily Digg-ing stuff are a few of my favorites. Below is a list of things you can do with a quick key stroke and typing a few letters…. this is taken from Mozilla Ubiquity Tutorial. Before you go just add the Ubiquity Firefox Extension & try it out while you’re learning. Very exciting, especially for people who rock the Google Apps.

In edit mode, you can edit the page like any document: Select text, delete it, add to it, copy and paste it. Issue ‘bold’, ‘italic’, or ‘underline’ commands to add formatting. Issue the ’save’ command to save your changes so they persist even when you reload the page. Issue ’stop-editing-page’ when you’re done to go back to the normal page viewing mode.
- “email”
Begins composing an email to a person from your contact list.
Currently only works with Google Mail, so you’ll need a GMail account to use it. Try selecting part of a web page (including links, images, etc) and then issuing “email this”. You can also specify the recipient of the email using the word “to” and the name of someone from your contact list. For example, try issuing “email hello to jono” (assuming you have a friend named “jono”).
