The show command displays HyperCard objects and elements.
Show menuBar displays the menu bar at the top of the screen (unless the screen is locked). Show titleBar displays the title bar on the card window if it’s been hidden. (Normally, the title bar is visible.)
Show groups displays a two-pixel gray underline for all text that has the group text style. (By default, the group text style is invisible.) The underline appears for grouped text in every field (in all stacks). Use the hide groups command to remove the underline.
The show card forms display the specified cards in the current stack in turn, beginning with the next card or the next marked card.
The other forms of the show command display the card or background picture, a window, or an object at a specified location on the screen. If the point is not given, the window or object is displayed at its previous location.
Showing a window makes it the frontmost window. With external windows, an external command or external function must first create a window before show will work on it. Show does not create windows.
