Select Command - return
Hello everyone,
A simple question which may have a suggested solution:
I am using, and loving, the select command in a ksh93 script on AIX 6.1 to present users with menus.
I have been successful in controlling all of key input by the users, I still have an issue with the RETURN key. When the menu is presented if the user presses the return key by itself the menu gets redrawn. If the user keeps pressing return the screen keeps getting full of the same menu over and over and it scrolls.
Is there a way to capture the fact that return was pressed by itself and take care of action needed in the do....done attached to the select?
Or alternatively allow the return to redraw the menu but on top the original one, and not append it to the screen after the PS3 prompt?
Hope you all have some suggestions.
Thanks, and a Happy New Year everyone !

tk_popup(3tk)						       Tk Built-In Commands						     tk_popup(3tk)

__________________________________________________________________________________________________________________________________________________

NAME

       tk_popup - Post a popup menu

SYNOPSIS

       tk_popup menu x y ?entry?
_________________________________________________________________

DESCRIPTION

       This procedure posts a menu at a given position on the screen and configures Tk so that the menu and its cascaded children can be traversed
       with the mouse or the keyboard.	Menu is the name of a menu widget and x and y are the root coordinates at which to display the	menu.	If
       entry  is omitted or an empty string, the menu's upper left corner is positioned at the given point.  Otherwise entry gives the index of an
       entry in menu and the menu will be positioned so that the entry is positioned over the given point.

EXAMPLE

       How to attach a simple popup menu to a widget.
	      # Create a menu
	      set m [menu .popupMenu]
	      $m add command -label "Example 1" -command bell
	      $m add command -label "Example 2" -command bell

	      # Create something to attach it to
	      pack [label .l -text "Click me!"]

	      # Arrange for the menu to pop up when the label is clicked
	      bind .l <1> {tk_popup .popupMenu %X %Y}
