pgAdmin4 Query Tool - queries

I am working on pgAdmin4's query tool to create our training material and while working came across few things which I wanted to know:

1) The editor also offers several features that help with code formatting:

• The auto-indent feature will automatically indent text to the same depth as the previous line when you press the Return key.
  
• Block indent text by selecting two or more lines and pressing the Tab key.
  
• Block outdent text that has been indented using the Shift+Tab key combination.
  
• Comment out SQL by selecting some text and pressing Control+K.
  
• Uncomment SQL by selecting some text starting with a comment and pressing Control+Shift+K.
  
• Shift the selected text to upper case by pressing Control+U.
  
• Shift the selected text to lower case by pressing Control+Shift+U.
  

For reference here is the link which says above mentioned bullet  works but when I tried last 4 bullets are not working in pgAdmin4 v1.0 where as it was working in pgAdminIII. 

2) I am not able to see + sign in query tool of pgAdmin 4 v1.0 . PFB screenshot from this link which shows + sign for inserting row into table :

So are these features not working in pgAdmin4 v1.0 or they will be available with new version ? If someone can help me with answers it will be of great help to develop the training material.
