; Corner( <Number of Corner> )
: For number ''n = 1, 2, 3, 4'' creates a point at the corner of the [[File:Menu view graphics.svg|link=|16px]] [[Graphics View]], for ''n = 5'' returns point ''(w, h)'', where ''w'' and ''h'' are width and height of the Graphics View in pixels. Always uses [[File:Menu view graphics1.svg|link=|16px]] [[Graphics View|first Graphics View]], even if second is active.
:{{Note|1=Corner( <Number of Corner> ) won't work inside other commands. Instead create eg <code>C_1 = Corner(1)</code> and use that.}}
; Corner( <Graphics View>, <Number of Corner> )
: Creates a point at the corner of [[File:Menu view graphics.svg|link=|16px]]  Graphics View (1, 2) which is never visible in that view. Supported values of number ''n'' are ''1, 2, 3, 4'' and ''5'' as above.
:{{Note|1=Corner( <Graphics View>, <Number of Corner> ) won't work inside other commands. Instead create eg <code>C_1 = Corner(1, 1)</code> and use that.}}
:{{Note|1=use <code>-1</code> for the [[File:Perspectives_algebra_3Dgraphics.svg|link=|16px]] [[3D Graphics View]]'s corners (available values for ''Number'': from 1 to 8); for ''n = 9'' returns point ''(w, h, 0)'', where ''w'' and ''h'' are width and height of the Graphics View in pixels; for ''n = 10'' returns point ''(w, h, 0)'', where ''w'' and ''h'' are width and height of the main window in pixels; for ''n = 11'' returns view direction (for parallel projections) or eye position (for e.g. perspective projection); for ''n = 12'' returns screen left-to-right direction; for ''n = 13'' returns scales for x, y, z axes.}}

; Corner( <Image>, <Number of Corner> )
: Creates a point at the corner of the image (number ''n = 1, 2, 3, 4'').

; Corner( <Text>, <Number of Corner> )
: Creates a point at the corner of the text (number ''n = 1, 2, 3, 4'').
