I’ve previously noted my disappointment with the array of trivial trinkets that have so far defined Gmail Labs. One of the most recent additions, however, finally adds something of use.

Quote selected text allows you to selectively quote and reply to one small part of a message. Like other email clients with this feature (Apple Mail springs to mind), you just highlight the text you want to include in your reply, hit the keyboard shortcut “r” to reply, and the compose template will be just what you selected. This is a simple but useful feature. Note that it only works in Firefox and IE right now. Safari and Chrome support is still in progress.
