/serversigns list [persist]
Use this command to examine the configuration of a ServerSigns-controlled sign or block. After issuing the command, right-click the sign to view it’s configuration which includes the list of action commands added defined that are invoked when a player right-clicks the sign or block.
The optional “[persist]” parameter may be specified as the value “true” (i.e. /serversigns list true). Doing so keeps your game client in “ServerSigns inspect mode” permitting you to continue right-clicking ServerSigns blocks to examine their status as well. Cancel this mode of operation by entering the command /serversigns void or return to listing signs singularly without persisting with /serversigns list.
