This plugin adds a command (that can be bound to a key) that adds a random number of dots in the input, making you look depressed, or overly thinking...
Load the plugin.:
Then use the command:
But since the goal is to be able to add the dots while typing a message, entering a command is not really useful. To be useful, this plugin needs to be used through a bound key, for example like this:
/bind M-. _exc_pointpoint
You just need to press Alt+. and this will insert dots in your message.
