Clicking Help on the top menu item, or using Alt-H displays a screen like the one below.

On most other screens, you can press Alt Function Key 1 to directly access help for that screen.

Notes:

• The current version is displayed at the top right - useful if you are reporting problems.
• Your practice's licence details are displayed at the bottom. If there is no current subscription, the nag message shown above will be displayed.
• It is possible to tailor this screen - see here.
