In previous versions of Dreamweaver (for Windows but presumably for other operating systems as well) and in pretty much any other text editor (except maybe for vi/m but including the one I'm using to write this message in now). I can select characters using shift plus the arrow keys and select words by pressing shift-control plus the arrow keys. It seems you now have to use shift-alt to select words. I don't want to have to undo about 25 years of habit just for Dreamweaver.
Please say this is an easy setting I can uncheck somewhere! Thanks!
That is an issue that has come up a lot lately...
Make sure to add your voice to the others here: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform and hopefully in the next release they'll put it back to normal.
