Scaling
Scaling an object resizes it vertically, horizontally or both. To scale and object, activate the
scale mode.
To resize a selection in scale mode, drag the handles at the corners or press < or > (the factor
for key scaling can be set in Inkscape Preferences).
You may also scale a selection by adjusting the parameters of the width and height boxes on
the Tool Controls bar
Rotating
Lock the width and height proportion with the lock toggle on the Tool Controls bar.
Hold Ctrl while dragging if proportion constraint is needed.
Hold Shift to use the center point of the object as the center of the transformation.
Dragging the scale handles with Alt scales the selection by an integer factor, i.e. up to 2, 3, 4,
etc. times the original size or down to 1/2. 1/3, 1/4, etc. of the original size either horizontally
or vertically (or both). * In some Linux distributions, you may need to adjust your meta-key
settings to make this work.
Rotating a selection is done in rotate/shear mode, and makes the selection turn around its
axis point or rotation center.
To rotate the object with the Selector Tool, drag the arrow handles which are found at the
corners or press [ or ].
