How can I quickly open the Attribute Table in QGIS?
To very quickly open the Attribute Table you can double click on any Layer in the QGIS Layers Panel.
By default if you double click the Layer in the Layers Panel, the Properties window opens.
To change this default action, open the General > Settings menu and then Canvas & Legend tab. Here you can change the Double Click action in Legend from Open Layer Properties to Open Attribute Table.
So now when you double click on a Layer in the Layers Panel the Attribute window will auto open.
