Switch Browser Tabs When Using Multiple Area Capture

Anybody got a down and dirty way to switch to a different browser tab when doing a multiple area capture?

The keyboard shortcuts CTRL+Tab and SHIFT+CTRL+Tab are a no go.
The capture selection is locked to the active tab

There are times I would like to capture objects on different webpages and have them be on the one single canvas.

I know I could make separate captures and then drag and drop from the tray on to the canvas
but thats a bit of another time suck.

While we are at it, I am unable to also scroll a page when using multiple capture.
Ideas??
