Elsewhere If the object being dropped represents an URL or an absolute filename, open the corresponding document in XMLmind XML Editor.

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.
