When creating hot spots in Help topics, Windows Help assigns a specific meaning to certain standard characters. These special Help characters are described below.
| Character | Name | Purpose |
| Asterisk (*) | Underlined hot spot | Specifies that the hot spot should be underlined only. The default green color is removed from the hot spot. |
| At sign (@) | Interfile jump | Specifies that the jump is to a topic located in a different .HLP file from the current file. |
| Exclamation point (!) | Macro hot spot | Specifies that the hot spot contains a Help macro to be executed. |
| Percent sign (%) | Invisible hot spot | Specifies that the hot spot should be invisible. The default green color and underlining are removed. |
| Right angle bracket (>) | Window name | Specifies that the topic is to be displayed in the specified window, either the main Help window or a secondary window. |
