When you click on image with the tool the Scaling Information dialog box is opened, allowing to change separately Width and Height. At the same time a Preview (possibly with a grid or an outline) is superimposed on the object and handles appear on corners and borders that you can click and drag to change dimensions. A small circle appears at center of the Preview allowing to move this preview.

[Nota] Nota

The Transform mode works on the active layer only. To work on all layers of the image, use Scale image.

Keep Aspect (Ctrl)

When you move a corner of the selection frame, this option will constrain the scale such as the Height/Width ratio of the layer will remain constant. Note that this doesn't work with border handles. Note also that it toggles the linking chain in the dialog.

Width/Height

Here, you can set Width and Height you want to give to the object. The default unit of measurement is pixel. You can change it by using the drop-down list. These values are also automatically changed when you drag handles in the image. If the associated linking chain is broken, you can change Width and Height separately.
