Windows 8/8.1 – Using your keyboard to control the mouse:
Most people think that a computer has to be operated only with the mouse and that, if you cannot use a mouse, you cannot use your computer. This is not the case. In fact your computer not only be operated entirely from the keyboard, but doing so can often faster and easier than using the mouse.
Method 1: Using the ‘Ease of Access Center’ in the Control Panel
This method has more configuration options than Method 2, but it is recommended for users with a keyboard and/or a mouse – the interactive elements are small and therefore difficult to tap. If you are using a tablet or a phone, you will probably prefer Method 2.
To open the ‘Ease of Access Center’ in the Control Panel
From a computer with a keyboard and a mouse
  • Press the ‘Windows’ key + U.
Or
  • Move the mouse pointer to the upper right hand corner of the screen to reveal the charms.
  • Click on the ‘Search’ charm – the one with the magnification glass icon.
  • Type the query ‘Ease of Access Center’ in the search box (Fig 1).
  • Click on the button ‘Ease of Access Center’.
From a touch enabled device

  • Tap on the ‘Search’ charm – the one with the magnification glass icon.

Apple to fix iPhone 6 Plus 'touch disease' for a fee: 

Apple has started offering a service to fix a fault on iPhone 6 Plus phones known as "touch disease".
Touchscreens on smartphones that have this problem gradually become unresponsive.
The fault was highlighted by gadget sites which said it was caused by a manufacturing issue that meant some screen controller chips became loose.
Apple was criticised by one expert who said it was the phonemaker's responsibility to fix it.
Apple is charging $149 in the USA for the service that will only be available on phones that are "in working order".

Loose chips

In a statement on its website, Apple said it had "determined" that displays on some iPhone 6 Plus handsets flickered or became unresponsive if the device was dropped several times on a hard surface and was then subjected to "further stress".
An iPhone 6 Plus suffering this problem, which worked and did not have a cracked or broken screen, was eligible for the repair programme, it said.
The service is available worldwide and costs £146.44 in the UK.
Apple said that customers who had already paid to get their phone cured of "touch disease" should get in touch to be repaid for the amount they spent beyond the programme fee.
The repair programmer will run for five years beyond the initial date on which the iPhone 6 Plus went on sale, said Apple.
Stuart Miles, founder of gadget news site Pocket-lint, said: "I think if it's a known defect that isn't caused by the user then it should be the responsibility of Apple to fix the phone free of charge regardless of the age."
The manufacturing problem with the iPhone 6 Plus was first highlighted by gadget site iFixit which said it had seen an "influx of faulty i Phones".
In a blogpost about the problem posted in August, iFixit said there were "pages and pages" of messages from aggrieved iPhone 6 Plus owners on the Apple support site complaining about the fault.
An investigation by iFixit and specialist repair shops found the cause of the fault was the placement of the touchscreen controller chip. Several rough knocks could dislodge this chip making phones unresponsive, it said.
