Remote Desktop Manager has lists of all custom variables, which can be managed in two different locations depending on their intended use.
To create, modify, or delete custom variables, go to File – Settings – Applications – Custom Variables. Each variable requires at least a Name and a Value. Note that these variables are user-specific and can be used in all data sources.
Alternatively, custom variables can be managed in Administration – Vault Settings – View – Variables. Each requires at least a Name, a Value, and a Description. All users that have access to the Vault Settings may see and use them, but they can only be used in that specific vault.
Custom variables will also appear in the Custom Variables subsection located under General in the Entry Variables window of the entry Properties, as shown in Access and manage variables.
