Keystroke(s) to disable QuickLaunch

QuickLaunch interferes with Scandisk, so I want to disable QuickLaunch before doing a ScanDisk. I’d like to do that by batch file (I KNOW the mouse clicks required), so I’d like to discover what keystrokes would disable QuickLaunch, as a first step to writing a batchfile to close QuickLaunch. Any help appreciated.
