You can create custom floating objects.
You can resize a floating object with the mouse or Shift + Arrow or Ctrl + Shift + Arrow keys. You can move a floating object by dragging it using the Shift key and the mouse.
You can use the right or left mouse button to select a floating object. You can also use the Tab or Shift + Tab key to select the object.
Normal shortcut keys for cut, copy, and paste apply to floating objects. You can use the Ctrl key and the mouse to drag and copy the object.
Floating objects can be imported or exported to XLSX or XML files.
The following image displays a custom floating object.
