Using access keys

On the tScheme web site we have used the UK access key standard on the most commonly used links and help features as listed below:

Setting the screen resolution

Screen resolution, measured in pixels, refers to the resolution of the computer monitor. The screen area setting is an important factor in how much information your monitor can display. A common setting is 800 by 600 pixels. By increasing the number of pixels your monitor displays, you can view more on your screen regardless of its actual dimension.

The tScheme site has been designed to work well on a screen resolution of 800 by 600 pixels. This means you should not have to scroll from side to side, but you may have to scroll down or up depending on the length of a page.

If you wish to change your screen resolution follow the instructions below, appropriate to your computer system.

Instructions for Windows 95/98/NT/2000/XP

  4. Open the Display section by either double-clicking on the Display icon or by highlighting the icon and pressing the Return/Enter key
  5. Select the Settings tab
  6. Move the screen area slider to the right until it reads 1024 by 768 or larger. If this resolution is not available on the computer you are using, choose 800 by 600. [Note that you will need to scroll more on web pages when using this lower resolution]
  7. Select OK to save changes
  8. After the screen resizes, select OK button again to confirm the new screen size

Or

  1. Minimize all open windows
