Action
Indents a block of selected text.
You need to select at least one line in order to use this option.
When you have a structure like :
Do
a=a+1
b=b+1
Loop
It is hard to see the structure. You can best indent your code.
Do
a=a+1
b=b+1
Loop
When you have code that is not indented you can indent it by selecting the two line within the structure and choose 'Edit Indent Block'.
