Drag one of the “handles” displayed around an image. (The “handles” are displayed after clicking on the image.) | Resize the image, but always preserve its aspect ratio. Pressing Ctrl (Cmd on the Mac) while dragging the handle allows to distort the image.
Drag a separator found between two table columns. | Resize the table column. More precisely this gives an appropriate proportional width (e.g. `<colspec colwidth="3*">`) to all table columns.
