Version: 2.0.0-SVN "Mars Pathfinder" (using 4.2.1 (KDE 4.2.1) "release 103", KDE:KDE4:Factory:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (i686) release 2.6.27.19-3.2-default Pressing F3 on a text file is expected to open a file read-only in the built-in viewer, but it opens a file editable in an editor with Save, Undo and the whole functionality as it would be opened in the built-in editor (F4). The only hint that there is a special F3 handling is the suffix "(Viewing)" appended to the file name displayed in the file's tab.
