How to send Ctrl-A, Del in CDP Mode?

[LeeMeng2020]

Sometimes I encounter fields with pre-filled or default text. On some sites, I also need to delete this text before I can key in new text. So I would like to send a Ctrl-A or a few Del to that field. Alternatively, I could do a double-click on the field which has the same result as Ctrl-A. How can I do this?

Note: I'm trying to send these keys or clicks in CDP Mode, not standard mode

Methods such as sb.cdp.type(selector, text) should automatically clear out text fields before typing in new text.
If for some reason that didn't clear out the old text first, use the PyAutoGUI methods instead.
