The edit menu gives you access to the common edit functions Cut, Copy, Paste, Delete. Depending on the window type active (screen window, log window, etc.) several other menu entries might be enabled.
Undo
If the active file has been changed and an undo operation is available the Undo menu is enabled. You can step back through your changes until you get to the last point the file was saved or loaded. Changes to a screen file are indicated with an asterisk after the window title.
Select All
For screen files this selects all items on the screen. This might be useful to identify all items since sometimes items can be "hidden". For example a bitmap display that is all white on a white background.
Find, Find Next, Replace
These options are enabled for log files and the console window only.
To Top, To Bottom
These options are enabled for screen files only and move the selected item(s) to the top of the z-order stack or to the bottom respectively.
Spread Horizontal, Spread Vertical
The Spread Horizontal and Spread Vertical menus let you distribute the selected items evenly within the selection range (for the hoizontal spread the selected items are distributed over the width of the selection, for the vertical spread the selected items are evenly distributed over the selection height).
