Spreadsheet SetAlias/en

Description
The tool opens a dialog to set up an alias for a cell. Instead of using the exact cell name like A2, B3, or C4, a custom name can be used.

Usage

 * 1) Make sure there is an active  open so that the button is enabled.
 * 2) Select a cell.
 * 3) Press the  button.
 * 4) Enter an alias:
 * 5) * Only alphanumeric characters and underscores ( to, to ,  to  and ) are allowed.
 * 6) * The first character must be a letter.
 * 7) * Using 1 or 2 capital letters followed by 1 to 5 numbers, for example, is not allowed as this is considered a cell address.
 * 8) * Character sequences that are units are not allowed. For example is an invalid alias as it is the unit for Watt. Since FreeCAD supports many units it is best to avoid short aliases. See Expressions.
 * 9) * Using the mathematical constants and  as aliases will lead to errors and should be avoided.
