The Mask popup menu can be overwhelming upon first encounter. However, if you follow the next
few steps you can create a single simple mask without having to understand every possible parameter.
+Be sure you are working in a Format that includes the Alpha channel, YUVA or RGBA, because you need
+to have transparency for masking to show or will end up with only a black area.
\begin{enumerate}
\item To define a mask, in the Compositor window click on the \textit{Edit mask} icon to get the popup Mask menu. If the menu does not come up, click on the \textit{Show tool info}.
\item On the video, LMB click on the place where you want to start a mask.

-The controls generally all contain a yellow colored tooltip when you mouse over the control, providing a hint of their function and shortcuts for usage.

The transport panel is controlled by the keyboard as well as the graphical interface.
For each of the operations it performs, the starting position is the position of the insertion point in the Program window and the slider in the Compositor and Viewer windows.
