There are 2 options (on applications which havn't overridden default key bindings) -
a) cmd-left arrow for beginning and cmd-right arrow for end of the line.
b)emacs key bindings are available as well
control-a and control-e for the beginning and end of a line.
Option a) gets slightly complicated in text entry on edit controls of browsers which have the cmd-left arrow key mapped to previous page (Firefox). In addition, a lot of multiplatform software ends up making things behave like on Windows ( Microsoft Office being one) by overriding defaults for these keys and home and end keys do take you to the beginning and end of the line there.
To my knowledge, Apple has never replied officially to any post on their company fora. It appears as though it is intended for Apple customers to communicate with others in the "community" - probably why they use that term in their fora. That aside, I've never understood their post policing strategy. Obviously someone at Apple has moderation duties.
As a manager who has hired people before, I don't see how this could replace a traditional resume. Resumes allow for me to quickly evaluate a candidate. I really don't care what my potential candidate's social media history is or any other arbitrary information (badges are nice, but as a recruiter I wouldn't know the scale nor why I should care). I do think something better than a resume is worth looking into, but the execution has to be right.
I disagree with this. I think most people are not looking for a cable alternative, but an alternative to DSL. Fiber isn't really helping because it's rate limited by the ISP.
