This operation takes a symbol and creates a directory with that name in the current directory. Directories are good ways to group related symbols together. Most times a symbol is looked up, the current directory is searched and then all parents are searched until the HOME directory is reached. So, you can rely on this behaviour to allow subdirectories to inherit some values from their parents.
In order to change to directory, you can select the "User" button on the calculator and press the button associated with the directory. Or you can just type the name of the directory and press Enter.
Note that directories are only supported on Halcyon Calc. Halcyon Calc Lite does not support directories.
