How to test NVDA screen reader behaviour on a Mac:

1. Download Microsoft Edge VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
2. Download Virtualbox and import the Edge VM image.

Then in the VM:

1. Install guest addons in the VM
2. Download & install latest NVDA from nvaccess.org
3. Download & install SharpKeys and use it to map left an alternative key (eg. Left Ctrl) to the Insert key. This is needed because Macs do not typically have an “Insert” key which is the prefix for many NVDA commands.

Setting up Pi Zero OTG - The quick way (No USB keyboard, mouse, HDMI monitor needed)

More details - http://blog.gbaman.info/?p=791

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH i
