This package allows you to interact with Leo.de dictionaries from within emacs.

It provides the command leo-translate-word. If no other phrase is entered, the word currently under the cursor is used. If the region is active, it is used (this also works in pdf-view-mode). It translates between German and the language set by the custom variable leo-language. The second language can also be specified interactively by invoking the commands with a prefix argument.

Results are sorted by part of speech, and display all additional information about the term such as usage, case markers, linguistic variant, etc. They also include a direct link to conjugation or inflection tables, shown as the icon ▦ (or #).

In the results buffer:

• click on a word to search for it
• n and p to navigate to next/previous entry
• <tab> to a word or phrase then hit <return> to search for it
• t or s to search again
• v to instantly search for the most recent kill ring item (paste and search)
• C-u t to search again and choose your language
• , and . to go to the previous/next part of speech heading
• f to jump to forum results
• click on a part of speech heading to view more results of only that type
• < and > to limit search to source/target language
• b to view results in external browser
• d to look up the term on duden.de
• l to look up the term on linguee.de
• k to look up the term in wiktionary-bro if installed
• and c to search the same term with dictcc.el if it's installed.
• ? to view these commands.

Links to forum results are also displayed. If you click or hit enter on one, it will be rendered in a basic way using shr. To view it in your browser, hit b.

If no results are returned, a list of suggestions is displayed which are also click (or tab/return) to search.

For the moment there is no functionality to return to previous result. The easiest way to do this is t for a new search, then M-p to scroll back through search history.

Available languages: en, es, fr, it, ch, pt, ru, pl.

The pairs tested while hacking on this are en < > de, plus a little fr < > de. Other languages may not work as well. The propertizing of entries isn't perfect, but it's good enough to rely on and is still being improved.

It looks like this:
