Settings

Open the tray menu and choose Settings…. Changes apply right away.

General

Start with Windows	Runs WinDict when you sign in. Also in the tray menu.
Show above Start	Opens the card on top of Start and Search. Only in the installed copy: see Above the Start menu.
Check for updates	Once a day. When there's a new version, the tray icon shows a dot and its menu has Update app.
Language	The language WinDict is shown in: English or Italiano. At first, the language of Windows, if WinDict has it.
Shortcuts	The keys that look up and translate, `Alt`+`D` and `Alt`+`T` at first. Click one and press the new keys; `Esc` keeps the old ones.

Card

Theme	System, Light or Dark. With System, the card follows Windows, and always takes its accent color.
Text size	From 80% to 200%. Also `Ctrl`+`+`, `Ctrl`+`-` or Ctrl and the mouse wheel on the card.
Definitions	Senses shown per part of speech, from 1 to 10. 4 at first.
Synonyms	Similar words under each part of speech, from 0, which hides them, to 12. 6 at first.
Examples	Sentences showing each sense in use.
Animations	At first as Windows has them, under Accessibility → Visual effects. Turn on or off to override it.

Lookup

Online dictionary	For pronunciations, and words the built-in dictionaries lack. Translations need it on.
Languages	The dictionaries words are looked up in. English is built in; choosing Italiano downloads its dictionary, once.

Read selections

How WinDict reads what's selected:

Direct only, the default: reads the selection directly, through UI Automation. It opens faster, but misses selections in apps that can't be read that way. Switch to Automatic if words go missing.
Automatic: reads the selection directly, and copies it in apps where that isn't possible, putting back what was on the clipboard. Works in every app.
Clipboard only: always copies the selection, which is slower. Try it if an app gives the wrong text.

Translation

Default languages	Translated from and into when the language can't be told: English into Italiano at first.
MyMemory email	Raises MyMemory's daily limit on free translations. It's sent only to MyMemory, with the text translated.

The settings file

The settings are stored in %APPDATA%\WinDict\config.json. To edit the file by hand, use Open config.json at the bottom of the settings window, then Reload settings in the tray menu.
