How does PAGE LOAD work?

I realise that it makes the program halt for the duration the page takes to load, but can't I just use sleep and just be fine?

Also, if I use page load, how do I use the select control feature in the page?

You can just use sleep action usually, but this is not perfect, I think you know it.

Page Load action is much better. After the Page Load action, you can add the select control feature.

"Page load wait" is an action used to determine if the page finishes loading by finding some controls in the page.

"Find Page Control" is an action that using some condition to find one html item, then you can save it or not. It is the same as "Find Control".

when all the controls have been found, the page finishes loading.

How to add "Find Page Control"? -- Move on the action "Find Page Control", then click Right button and select "Insert Find Page Control"
