A gray menu command typically indicates that the option is currently unavailable or disabled within the application or software. This can occur for various reasons, such as the user not having the necessary permissions, the required conditions not being met, or the function not being applicable in the current context. Users should check for any prerequisites or conditions that need to be satisfied to enable the command.

sub-menu
A check mark next to a menu command typically indicates that the command is currently active or selected.
