In OSX (maybe other OS's) you can select text in the following manner:
When you double-click on a piece of text you can extend the selection by using the Shift key and either the Right or Left Arrow key.
The initial arrow-key press determines the direction of the selection (right or the left), when more text is selected.
I hope my explanation makes sense.
This feature works everywhere in OSX and I love the intuitive way it works.
I really really miss this in ST. (Even works in BBEdit)
Perhaps it's a setting I haven't found yet, but if it is not available I would like to request this feature. (I posted it here before I make an official request on Echo)
ps. Just learned about Sublime Text last week and absolutely love it. Thank you, thank you!!
