Focus the search box when returning from another app, or typing some letters

[Kapis]

It will avoid this way to have to click on the search box and select all the content to type a new word.

[Kapis (capiscuas)]

When typing any key from the list of words or the article view, it will focus on the search textfield adding that new word.

Concern: We have to avoid the combined words to be captured too, like CTRL + C , CTRL + V, so users can copy text.

Modifiers Ctrl + or ALT + are not captured (they will keep their normal behaviour).

Thing left. Focus the search box when returning from antoher app.
