 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 *orthagonal* coordinates is to specify a distance and then a direction with an arrow key, up, down, left or right while holding the [Crlt] key.  Placing the second point of a line can be done by entering a numerical value for the distance and then press [Crtl]-[|leftarrow|] to place a point to 180 |deg| from the reference point.

 Text input may also be required for **Tool Options** where distance, angle, etc. are needed with some of the **Drawing Tools**.
