 LibreCAD offers an additional method for entering *relative coordinates* when using the numeric keypad; type two decimal points ("**..**") in lieu of the comma between the X and Y values.  For example, "10..20" is equivalent to typing "@10,20".  Refer to the **User Guides** for more details on using the :ref:`command line <cmdline>`.
 
-Another alternative when using the keyboard for defining a relative *orthogonal* coordinate is to specify a distance and then a direction with an arrow key; up, down, left or right while holding the [Crlt] key.  After placing the first point, the second, or subsequent, point can be placed by entering a numerical value for the distance and then press [Crtl]-[*Arrow*] for the direction.  For example, after specifying the first point, type "100" and then [Ctrl]-[|leftarrow|] to place a point to 180|deg| from the reference point.  This method works with line, circle, arc, etc. where a "next" point is required.  The arrow keys are equivalent to the following angles:
