 `<p0..h>` can be optional extended with a dedicated position of the tilt if a venetian blind is configured and supported. The position of the tilt can be added after the normal position with a `/` as seperator. This is optional. Example: `shutterbutton1 1 100/-90 50/0 75/-90 100 - - 1 1`. Tilt and position also support increment or decrement position from current state with `--`oder `++`.
 
-By a button single press the shutter is set to position `<p1>`.  Double press will drive the shutter to position `<p2>` and  triple press to position `<p3>`. Holding the button for more than the `SetOption32` time sets the shutter position to `<ph>` max if button is hold until position. If the hold button is released during the shutter moves the shutter will stop. Any button action `<p1>` to `<ph>` can be disabled by setting the parameter to `-`. Independent from configuration `<p1>` to `<ph>` any press of the button while the shutter is moving will immediately stop the shutter.

+Ensure that you set a value higher than 5 for `SetOption32` (0.6 seconds is the minimum possible time). Lower values will not trigger the hold action for `ShutterButton`, and the shutter will not move.
 
 Global steering of all your shutters at home is supported by additional MQTT broadcast. By any button action a corresponding MQTT command can be initiated to the `<grouptopic>` of the device. For single press this can be enabled by `<m1>` equal to `1`, disabling is indicated by `-`. Double to hold MQTT configurations are given by `<m2>` to `<mh>`, correspondingly. When `<mi>` is equal to `-` only `cmnd/<grouptopic>/Shutterposition<x> <p1..h>` is fired. When `<mi>` is equal to `1`, `<x>`=`1..4` is used to control any shutter number of a Tasmota device having same `<grouptopic>`.
