Since Ver.10.4 of DA, the "Unrecorded Instant Click" item has been added when you perform a right-click in the Recorder View.
"Unrecorded Instant Click" is a function that performs a click (e.g. on a link or on the「×」button) without creating a step inside a Desktop Automation step. ※Not implemented in Ver.10.3 and earlier
It is however not limited to controlling DA terminals as it can also be used to control Chromium or Built-in-Excel for example, through a Desktop Automation step.
Example of use
Closing an application originally open in a DA terminal without controlling the DA terminal itself but by simply clicking the「×」button with an instant click.
