 - `hook` - This argument specifies which hook or event the trigger should listen for. WeeChat is built as an event-driven platform, so pretty much anything from mouse movements to IRC messages are handled via events. In this case, we want to trigger on the `print` event, which is fired every time a new message gets received from IRC.
 - `argument` - The argument is needed for some hooks, but not for the `print` hook, so we are going to ignore that one for now and just set it to an empty string `''`.
 - `condition` - The condition must evaluate to `true` for the trigger to fire. This is helpful because the `print` trigger fires for every new message, but we only want to be notified when the new message mentions our nick. The condition for this is `${tg_highlight}`. You can find the list of variables that you can access with the command `/trigger monitor`, which prints all variables for every trigger that gets executed.
-- `variable-replace` - This took me a while to understand. This command is used to manipulate data and save it to a variable. The syntax is inspired by the sed command. Explaining it fully is out of the scope of this blog post, but you can take a look at the [docs](https://weechat.org/files/doc/devel/weechat_user.en.html#trigger_regex). In our example, we replace the whole content of the variable `tg_message` with the format string `${weechat.look.nick_prefix}${tg_prefix_nocolor}${weechat.look.nick_suffix} ${tg_message_nocolor}` which results in a sting like `<tiim> Hello world!`.

 - `command` - The last argument is the command that gets executed whenever this trigger fires. In our case, we use the `/execute` command, which starts the wget command which in turn sends a post request to ntfy.sh. Make sure you set the ntfy topic (the part after `https://ntfy.sh/`) to something private and long enough so that nobody else is going to guess it by accident.
