If you type a word into the Search field, the translation will be looked up either in the german or the english dictionary. If you leave the field empty ksteak will automatically use the last clipboard entry. So you can easily select a word in another window and call ksteak which translates the selected word. The use of german "umlauts" is allowed. If you want to translate more than one item, you have to quote these items with double quotes.
The gender of the nouns is handled in the following way:
masculin, male
feminin, female
neutrum, neuter
plural
Hint: You can use the letters "f", "m", "n", "pl" in order to search all nouns of the same gender. You should use the context option in order to find all entries.
