         DELAY

Command: #delay {seconds} {command}
Command: #delay {name} {command} {seconds}

         Delay allows you to have tintin wait the given amount of seconds
         before executing the given command. tintin won't wait before
         executing following input commands if any.

         Floating point precision for milliseconds is possible.

Example: #show first;#delay {1} {#show last}
         This will print 'first', and 'last' around one second later.

Comment: If you want to remove a delay with the #undelay command you can add
         a name as the first argument, be aware this changes the syntax. If
         the name is a number keep in mind that delays with the same numeric
         name will not be overwritten
