Add Custom Variable
Clicking this allows you to Add Custom Variable items to be used with the theme.
This will create the "placeholder" variable
custom_variable. Clicking on the text of the custom variable will open its editor window.
Entering the appropriate values for the variable name and its value then clicking on the variable name above the fields will close the dialog box and save the custom variable.
Clicking on the
X beside the custom variable name will remove it from the theme.
