When true, wc3270 will run in auto-shortcut mode.
In auto-shortcut mode, wc3270 automatically creates a temporary desktop shortcut (.lnk file) that is compatible with the options in a particular session file, starts the link, and exits.
Session files created by the wc3270 Session Wizard include setting autoShortcut to true. Desktop shortcuts created by the Session Wizard and by auto-shortcut mode itself include the +S command-line option in their Target field, to prevent an endless loop of auto-shortcuts.
Introduced in wc3270 3.3.10.
