Wake on Lan Teamviewer Manual missing menu item

[oldcelt]

I've followed the Wake-on-Lan Teamviewer 9 Manual (most up-to-date?) until I reach page 12 - "Wake up the computer".

Steps 4 and 5 say:-
"4. Select the offline computer that you want to wake up from the Computers and Contacts list.
 5. In the context menu (right click) tick the Wake up button."

I have no context menu (running Teamviewer 13) to click on!

What do I do please?
