You can abbreviate the root keys of the registry. For instance, instead of "HKEY_LOCAL_MACHINE\Software" you can write "HKLM\Software", etc. Here is the complete list of registry shortcuts:
| HKCR | HKEY_CLASSES_ROOT |
| HKCU | HKEY_CURRENT_USER |
| HKLM | HKEY_LOCAL_MACHINE |
| HKU | HKEY_USERS |
| HKCC | HKEY_CURRENT_CONFIG |
