[GIS] Polyline split at node in QGIS

Question

How can I divide a polyline at a specific node with QGIS (version 2.12.3-Lyon)?

I was looking for something similar to MapInfo tool "Polyline split at node" which is this simple:

1. Make your layer editable
2. Select the polyline to be splitted
3. Click on "Reshape" (which shows all nodes)
4. Select the node where you want to split the polyline
5. From the menu "Objets" select "Polyline Split at Node"

Answer 1

QGIS can do the same. On the Advance Digitizing Toolbar is the 'Split Features' button:

It appears more simple than MapInfo.

1) Make the layer editable

2) Select the 'Split Features' tool

3) Select the node you wish to split at.

This work with polygons also.
