12.3. Context Help
The Context Help command makes the mouse pointer context-sensitive and changes its shape to a “?”. You can then click on a window, dialog or menu entry and GIMP displays help about it, if it is available. You can also access context help at any time by pressing the F1 key while the mouse pointer is over the object you would like help about.
