SDL Trados Studio 2019 introduced "Tell Me" functionality, which helps you find features in Trados Studio. 

Another benefit of this functionality, is that it includes an API, which allows developers to add to the functionality of Trados Studio 'Tell Me'

The QuickInfo plugin does just that, by extending the default "Tell Me" functionality to provide various useful bits of information such as unit conversion, maths calculation, airport codes, Unicode description and more.

Simply click on Tell Me and start your search query with '@info' and then the additional query- for example-

This is really useful when you need a quick calculation/conversion whilst translating, without the need to open your browser.

Trados QuickInfo supports  for example-

• Unit conversion
• Currency conversion
• Hex/Decimal
• RGB> Hex > RGB Colour
• Airport codes
• Color

and a number of misc items.

The plugin is also opensouorced providing a great tool for other developers as they can see how this functionality is used, or even contribute to this one with new bits of helpful information to extend its usefulness.
