Difference between page actions and control actions

This is a very simple approach but most of the beginners get confused on these things often while designing page.

If we go to any container with cuegroup. We can see in "View" toolbar -  page actions and control actions.

Always, page actions and control actions behave same at the last line( 1st empty line).
However,

Page Actions:

• page actions can be seen when you navigate through different areas as shown below.

The design of page is simple select any page and go to design -> view -> page actions as shown below.

Control Actions:

• Control actions can be seen on role-centered page. 
• Control actions appear only in Cue group as shown in screenshot below.

You can view the design of control action by selecting the cuegroup and choosing the control actions in -> view -> control actions.

fig. below would express the design in a better way.

As shown in the fig. below go to design of Cuegroup page, select the cuegroup, go to view tab and select control actions. You can see the control actions defined here.
