I am new to QGIS.
Can I find a location on the map I'm working with by entering its coordinates?
If yes, where do I enter these coordinates?

I think I found the answer. There is a Question here
So I wrote:
boxControl.on('boxend', function ()
{
var a= boxControl.getGeometry().getCoordinates();
$('#taOzet').text(a);
});
and it's returned:
3524005.462580891,4941742.299355211, 3524005.462580891,4609088.352258123, 4069460.0964239086,4609088.352258123, 4069460.0964239086,4941742.299355211, 3524005.462580891,4941742.299355211
there are 5 points with x-y coordinates also 1st and 5th ones are same, so they make a polygon, in my case a rectangle! Thanks again.
I can propose a (lengthy) solution using existing tools in QGIS.
Assumption:
- The area is not large and the computer used to perform this is pretty powerful.
- The "Grid statistics for polygons" output and the "Elevation raster" files are available.
Steps:
- Use the "Grid values to points" tool to generate a point file for the concerned area. (Select options as shown below)
[Warning: This output point file can become very large for large areas or high resolution elevation data; and will make your computer non-responsive. Please try on a smaller area / dataset first.]
- Perform "Join attribute by location" on points layer created in step 1 (target layer) and the "Grid statistics for polygons" output (join layer).
The output from step 2 should have geometry columns (lat & long), ID and minimum elevation of the corresponding polygons. A simple attribute query or sorting based on elevation will help you select the point having minimum elevation in each polygon.

On the bottom of the application you can set extent or the center of the map.
It looks like this:

The first button switches between extent and map center.
