Hi people !

I'm french, so I apologize for any errors of English. Maybe I will not use the appropriate technical terms (especially since I have a French version of Scribus), but I'll try to be as clear as possible in my questions.

How to research text and move into the document at the same time?
Let me explain: I have a document that is over 300 pages, full text, and I have to correct a lot of stuff in it. The problem is that when I do a research, it can detect (and select) the text, but without the view! The document remains where it was when we opened the search window, even if the search text is located up or down. (I've never seen it on any software, usually, the searching function go directly on the detected text and show it so we can see it.)
Worse, we can not even move in the document while the search window is not closed!

If I have to open and close this window each time and every time moving in the document again, this document is over 300 pages, I'll spend my life it and lose an incredible time!
Can you help me ?

Subsidiary questions:
Is there a keyboard shortcut to switch to preview mode?
How to hide the status bar at the bottom that displays the X and Y position of my cursor?
Thank you.

(NB : I know...I realized maybe too late that I should correct the text BEFORE the layout, on another soft...)
