The ability to mark the computational range to perform revelant algorithms
in only parts of the map im intrested of will really help speed up my
workflow.
At the momment there is the option to set the region from current display
extents (through the zoom option button), but there is not any way to
visualy mark the region I am intrested in by drawing a rectangle (to get
the extents) for example.
You can also set the region manually with g.region but its prone to human
error (you can easily miss a digit)

Comment(by hamish):
see also qgis-grass toolbox where a red bordered box is used to show the
computational region, and the d.region.box addon (just shows another
region).
take care to align the ew,ns resolution if doing this, but if multiple
rasters (or no rasters) are present, which to take it from? or preserve
current computational region's resolution?

Yeah, I know about that module but im not sure if you can specify the region.
Usually I identify visually a spot in my raster where a certain algorithm needs to be run. mostly holes that need to be filled with r.fillnulls. So I don’t need it for the hole raster. Just for that spot. So preserving the raster’s resolution makes sense. Plus its trivial to change it the res flag of ‘g.region’.
If you have to do that more than three times, its too time consuming to querry the edges, and then plug them in g.region
What I had in mind is more like a functionality like the ‘zoomIn’ button, but instead of zooming in, it should change the computational extents of the rectangle you draw.

Can you please test and comment on ''Set computational region extent
interactively'' available in ''Map Display'' window under ''Various zoom
options''? If this is what you want, please close the ticket. (Martin
implemented this feature some time ago.)

* status: new => closed
* resolution: => fixed
Comment:
Closing as fixed. Available in but trunk and release branch 70. Tested in
both.
Possible improvement is switching on ''Show computational extent''
automatically or writing g.region -p to command console (and history file)
but these are separate requests which need more feedback.
