Description Bachue 2011-06-11 21:09:52 UTC
I always press tab by accident, and the document scroll to top. I think it is abnormal.

reproduced in 3.6.1 on Fedora 64 bit
To reproduce: open read-only document, scroll it some pages, press Tab
To create such document use File->Properties, tab "Security", enable "Open file read only", press Ok, then File->Reload.

If hyperlinks are inserted in your document, the behaviour is different: Press tab jumps to the next occurence of a hyperlink. May be this is intended. But then it is not obvious at all and it's not documented in the help. For me this is buggy as well.

Hi All, 

Currently key input action for read only mode is defined at:
https://opengrok.libreoffice.org/xref/core/sw/source/uibase/docvw/edtwin.cxx#2162

Harald is correct about hyperlinks being traversed. This is the default action if one of two conditions for tab key action in read only mode are not met.

First a check is made to determine if a Graphic, Frame, Ole, DrawObject, or DbForm object is selected. If so, tab/shift tab will move to the next/previous object of these types.

Second a check is made to determine if there is no multiselection and if the cursor is inside and input field. If so, tab/shift tab will move to the next/previous input field.

I tested the first check by: 
1) inserting some shapes and frames into a document
2) saving the document
3) setting the document in read only mode
4) selecting a shape 
5) pressing tab to moved to the next shape or frame.

I did not test the second check when an input field is selected.
