        in columns of tab separated database exports.
-  FIX: unexpected cursor jump on re-edit after repeat edit.
        on this sequence: repeat edit, close editor,
        re-enter editor, the cursor jumped unexpectedly
        to the position of last repeat edit.
-  fix: error message "OR not allowed after NOT" is now
        shown directly near the find mask.
Revision 4:
-  add: config file option "esccloseapp" to disable
        unwanted application close on escape key.

        into a left side filtered view produced empty screen.
Revision 3:
-  add: pressing SHIFT+BACKSPACE now does the same
        as INSERT: instant reset of find or path mask.
-  fix: running dview with a predefined area,
        then resizing the window beyond that area
        produced unreadable window content.
-  fix: dview did not adapt to enlargements of
        current desktop resolution.
-  fix: right click on blank space: if target window
        contains a filtered view, filter is now closed
        to enforce a full mirroring of the source text.
-  fix: one click edit: no longer enters edit mode
        when clicking on blank space left near text,
        thus reducing unwanted edits massively.
-  fix: dview for linux, mac under wine: in linux mode,
        dview now blocks unwanted character inserts
        while cursor keys are pressed.
Revision 2:
-  fix: one click search didn't work.

        set location filename [-bottom] jumps to the 
        given file's content top or bottom.
        run -min ... now hides the window which is often
        opened while executing commands.
        the same applies for runback -min[imized]. 
-  add: option -lean, config option startlean to open
        the first window non-maximized and centered.
-  chg: user scripts on hot keys:
        echo now also prints status into the status line.

        when the mouse was slightly moved.

        are now kept across reloads.

        invisible, is now shown like a tooltip.
-  fix: tooltip display over buttons: when mouse was moved
        the tooltip immediately disappeared even while 
        staying on the same button. with mouse devices
        that send too many events, the tooltip disappeared
        nearly instantly.
-  fix: double click detection was nearly impossible
        with some high resolution mouse devices.
        now, if clicking within text, the mouse surf
        is blocked for better double click detection.
-  fix: double press of right Alt key highlighted words
        the same way as with double Control key press.
        as Alt is often used when typing text, 
        this is now disabled.
