Configuration
tab-complete-enabled
Default: true
Controls tab-complete in chat. In command mode, tab can be used immediately after slash ( / ) or slash followed by one or more characters to list all commands even if the player does not have permission for those commands. When in chat or command mode after space has been typed, player can iterate through other online player names. Setting tab-complete-enabled to false will completely disable tab-complete in chat and command mode.
slash-tab-enabled
Default: false
Controls /<tab>. Using /<tab> lists all commands even if the player does not have permission for those commands. Setting this to false prevents listing commands using /<tab>. If tab-complete-enabled is set to false, this setting is ignored and players cannot use tab-complete at all.
slash-help-enabled
Default: true
Controls /help. When set to false, prevents the use of /help.
slash-question-mark-enabled
Default: true
Controls /?. When set to false, prevents the use of /?.
convert-question-mark-to-help
Default: true
Converts /? to /help. PermissionsEx can be configured to prevent a player from seeing help for commands the player does not have permissions for. This does not effect the /? command. Setting convert-question-mark-to-help to true will ensure the player cannot use /?.
no-help-message
Default: No help available.
Message displayed when /help is used but slash-help-enabled is set to false.
no-question-mark-message
Default: No help available.
Message displayed when /? is used but slash-question-mark-enabled is set to false.
