Ubuntu - How to draw the zone box???

[JavaBen]

I've searched, but all the documentation assumes I know how to draw the alarm zone, so it's not defined.

I saw one document that said: "I use a mac - I simply hit Cmd+Shift+4 - that brings up a screen capture cross hair and as I draw the box, I see its width and height."

How does one draw a box in Ubuntu, or Linux (no Mac) on the image of the monitor in Zones?

Thanks!

When you click add new zone, it should have the entire box highlighted in RED, with 4 green dots in each corner. You can move these dots to draw the box; and at the bottom of the page you will see where each dot has it's x and y coordinates, and next to each is a plus and a minus sign. If you need a shape other than square, you can add points in between existing points and then move those. If you hover over the green dots, they will tell you what point/vertex number they are so you can see which two points you need to add between.

You are exactly right!

I was zoomed out too far to see the green dots!

Thanks!
