Okular
is a document viewer. The specific utility that I want to show you is
that thanks to Okular you can work on documents in PDF format.
If
you usually work with Linux, you can find the program and install it
in the Software Manager.
Once
you have installed the program, when you open it, you will see the
following screen.
Now
you can open the file that you want to work in clicking on "file"
and looking for the document in your folder. I chose a legal
translation text that talks about marriage contracts in German. This
is an exercise that can be very helpful for translators, for example,
to mark and remove vocabulary of a text and make notes or marks that
later will help you for the translation.
In
the top menu "tools" you will find the "review"
function. When you press it, it will appear some tables on the left
side of the document, that you have to select to make different marks
on the text.
Among
the functions that you can use, you can add notes to the document,
highlight text and replace text, make freehand marks, underline text
or make straight and different ways marks.
