I was amazed that QGIS doesn't have a button to simplify this critical function. Thank you Christine, I do appreciate the response. I found a script that makes a new composer and then zooms to the extent of the map canvas in the new composer, but the script is not ideal (dependent on objects that won't always be present e.g. the filename of the QGIS template). Ideally one should be able to create a new button on a toolbar and then simply associate the 'Set to Map Canvas Extent' function with the button. If that is not possible I guess the next best thing would be a python script that does the same i.e. zooms to the extent of the map in the active composer.
I teach basic GIS skills to non-technical people and without this simple function it will be very hard to make any progress. Even the default procedure is too complex for them to remember. I strongly suggest that QGIS developers look at this. I really expected the 'Refresh' button to refresh the zoom extent as well. Why wouldn't a user want to refresh the zoom extent when refreshing the display of layers? It doesn't make sense to me. If anyone can help with that script I'd be grateful.

Dear Willem, you don't need to create a new composer. Procedure may depend on your QGIS version, in elder versions the window to select an item may be missing. First select the map item in the composer view (right column). In the item properties tab (below) scroll to the extents section. There you can find the two buttons "set to map canvas extent" and "view extent in map canvas". Click the first one to transfer your map window extent coordinates (your "view") to your composer map extents (your "composer"). That's what you wanted to do as I understand it. With the second button you might do the reverse: transfer the composer map extent coordinates (your "composer") to your map window (your "view").
