 == About Control points ==
 [[Control points]] are central to [[Panorama Tools]] and [[hugin]], because they are used to estimate the position of image position and lens parameters described above.
-A control point specifies a corresponding point between two images. Using these corresponding points, the [[hugin Optimizer tab]] can estimate the image position and lens parameters.
+A control point specifies a corresponding point between two images. Using these corresponding points, the [[hugin Optimiser tab|Optimiser tab]] can estimate the image position and lens parameters.
 It is therefore important that the control points are accurate and usually at least 3 well distributed control points should be used to estimate the image position ([[yaw]], [[roll]] and [[pitch]]) and maybe the [[Field of View|HFOV]].
 For accurate estimation of the a,b,c distortion parameters, many well distributed control points, and a large overlap (up to 50%) are required.

 The keyboard short cut for the '''fine tune''' function is the '''f''' key.

-The size of this neighbourhood can be controlled by opening the [[Hugin Preferences]] panel and setting the '''Local area search width'''.
+The size of this neighbourhood can be controlled by opening the [[Hugin Preferences|Preferences dialog]] and setting the '''Local area search width'''.
 Note that the fine tune function estimates the translation of the patch around the point selected in the other image with respect to the current image.
 This works well if the rotation between the images is small and narrow angle lenses have been used.
-If wide angle or [[Fisheye Projection]] images are used, rotation search should be activated in the [[Hugin Preferences]] panel.
