Keyboard Equivalent for Screen Click?

[Box134]

When navigate to a new web page I often like to use the space bar to scroll
down. Only it won't scroll until I mouse-click the screen first. Is there
any keyboard equivalent for a screen mouse-click? Haven't been able to find
one.

Ctrl + Tab moves between elements.

Alt-Tab will allow you to set the windows focus. This might help you.
