In LO Writer, pressing the Shift Key + Page Down (or Up) should select a page length of the Document -and further presses of the Page Down/Up key should simply extend the selection.
However, in my Version 18.104.22.168 on Ubuntu 12.10 the 1st page is selected but further presses of the P/Down/Up keys results in a deselection of all the text and the cursor moving a page length in the direction requested. The failure is not related to if the selection has to go across a new page or not.
The Key Bind is seems correct or the 1st event would not happen on the 1st key press.
I use this method frequently to remove several pages from texts and the only work round I have found is to use Shift + Down Arrow until the whole area to be removed is selected.
Is this a bug in the 3.6 series or a settings problem? I did try a removal and reinstall to no avail. I know this did not start until I recently upgraded from Ubuntu 12.04
