            Bug ID: 141800
           Summary: Key assignment for modifier keys in Draw have
                    collision (on Mac)
           Product: LibreOffice
           Version: 6.3 all versions
          Hardware: All
                OS: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Draw
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: birnbach at posteo.de

Description:
Modifier keys change object movement during dragging:
* SHIFT: restrict movement to hor/vert ±45°
* CMD: duplicate object
* ALT: disengange raster, allow precision positioning

Modfier keys also change object manipulation:
* ALT: symmetric resizing (outwards from center)

Modifier keys also apply to object creation. E.g. when drawing a polygon,
holding ALT will while clicking will create a new point but hide the line
between that point and the previous point.


The ALT key is assigned to precision mode AND other purposes. Therefore,
certain operations are not possible on the Mac.


Examples of impossible operations:
* symmetric resizing of an object 
  (precision positioning takes precedence)
* precision positioning a point while drawing a polygon
  (line hiding takes precedence)

Steps to Reproduce:
1. draw rectangle
2. zoom in to 400% to better see object raster later
2. press ALT
3. click and hold corner point
3. resize rectangle

1. use polygon tool
2. place first two points
3. press ALT
4. place another point

Actual Results:
For rectangle resizing: raster is off, corner point can be moved
For drawing polygon: point is placed but no line to it can be seen

Expected Results:
For rectangle resizing: resizing of all corner points with respect to centre
For drawing polygon: precision positioning of point


Reproducible: Always


User Profile Reset: Yes



Additional Info:
The modifier key for disengaging the raster should be changed so that there is
no collision. The Control key (CTRL) seems unused in Draw so far. 

I first saw this problem in 6.3 but did not check back on earlier versions.
