GEDCOM Validator supports several accessibility features to help all users make best use of the application:

High DPI and display zoom

GEDCOM Validator is high DPI aware.  This means that the user interface scales correctly and renders crisply, be that on a 4K monitor or a small laptop screen.

With display zoom, you can customise the size of the text and controls in GEDCOM Validator.  This helps to make things easier to read on high resolution screens and gives easier navigation on touch screens.

You can change the zoom level with special keyboard shortcuts (the control key+the plus key to increase, the control key+the minus key to decrease, or the control key+the zero key to reset the zoom) or manually in Tools⯈Options⯈Themes.  The default setting is 100% which represents no zoom, and you can increase this up to 450% according to your needs.

Text size

You can increase the size of the text everywhere in GEDCOM Validator.  This helps to make text easier to read without scaling the entire user interface.  You can also choose to apply any system wide text size settings.  Text size can be configured in Tools⯈Options⯈Themes.

Colour filters

Colour filters are designed to make it easier for people with colour vision deficiency to differentiate between colours such as red and green, or make it easier for people with light sensitivity to use the application.  Colour filters can be configured in Tools⯈Options⯈Themes.  Several options are available:

  • Invert
  • Greyscale
  • Greyscale invert
  • Protanopia (red-green, red weak)
  • Deuteranopia (red-green, green weak)
  • Tritanopia (blue-yellow)

Keyboard navigation

GEDCOM Validator has full support for navigation by keyboard where use of the mouse is not possible.  GEDCOM Validator uses the standard Windows keyboard navigation shortcuts.  The following commands will enable you to use the application without a mouse:

tab key  Navigate to the next control.
shift key + tab key  Navigate to the previous control.
ctrl key + tab key  Navigate to the next control when focus is captured.
ctrl key + shift key + tab key  Navigate to the previous control when focus is captured.
shift key + F10 key or menu key  Open a context menu for the current control.
F10 key or alt key  Give focus to the main menu.
enter key  Activate a focused item.
alt key + down key or F4 key  Expand a drop-down list.
space key  Toggle the selected state of an item.
F1 key  Activate contextual help for the current control.

Screen readers

Screen readers allow blind or visually impaired users to read the text that is displayed on the computer screen with a speech synthesizer or braille display.  GEDCOM Validator is supported for use with screen readers which are compatible with Microsoft UI Automation, such as Windows Narrator.


GEDCOM Validator includes several dyslexic friendly typefaces which can increase text readability for people with dyslexia or dyslexic tendencies.  You can use the control key+the D key to toggle between the current dyslexic friendly font and the default font.  A dyslexic theme is also available which uses a lower contrast colours for all screen elements to reduce glare.  You can change the application theme using Tools⯈Options⯈Themes.

Contrast themes

Contrast themes alter the colour contrast of some text and images on your computer screen, making those items more distinct and easier to identify. GEDCOM Validator has full support for the system wide contrast settings in Windows.  You can also choose from one of nine built in contrast application themes if you prefer to use contrast themes only within GEDCOM Validator.  You can change the application theme using Tools⯈Options⯈Themes.

Light level

The application theme can be changed to according to the light level of the environment where the application is being used. A dark theme may be more suitable in brighter environments. The theme can be quickly toggled between light and dark using the task bar thumb button.
