Start by reproducing the Shift-Escape sequence in Apache NetBeans 24 on Debian with JDK 17, including the source editor, bottom panel, and search results panel. Investigate the behavior around maximizing the window and panel tab state; done means repeated Shift-Escape presses leave the panels and search results correctly displayed.
