Sometimes Certify's "Waiting For Execution" and System "Wait" dialogs will cause the focus to be lost from an HTML dropdown.
When this happens, it is recommended that the user should first try using the "Input Into Cell" Table action and
use the "Input Type" = "Select From DropDown".

If
this is a complex drop down that is not supported: the step will fail.
If
"Input Into Cell" doesn't work the user can try "Select Cell" to click
the cell and use Select Cell's "Followup Keystroke" parameter to
issue b{ENTER}.
The
"Followup Keystroke" parameter has a list of keys to choose from, but you can
type in anything that you could type in to the "ActiveWindow" "Send Keys"
"Keys" parameter.

This
may select from the cell's drop down in one step.
