Most of the time, either name can be used. However, when adding macros to the Contents tab or a SHED file, the short name must be used. Macro names are not case-sensitive. Most macros have specific parameters that must be entered. If the macro doesn't require specific parameters, you must still include the parentheses.
Some macros require several parameters.
Depending on the macro, you may use another macro as a parameter. When required, quotes enclose individual parameters. They are typically not required if the macro is in a topic or project file. Check your syntax and verify that you typed the single open quote under the tilde, not the single close quote under the double quote. RoboHELP makes entering basic macro information fairly easy.
