Edit

 

• Undo 
  Sets the workspace to the state it was in before the last Clear Block or Clear All event. If a block has been inserted or removed in the mean time, this menu item is disabled to avoid losing this change.
• Redo 
  Undoes an undo.
• Cut, Copy, Paste, Delete, Select-all      
  When the cursor is in an edit area, these standard edit items perform their usual tasks. However, when the cursor is outside of an edit area, in the workspace, their meanings change slightly. Cut and delete, for instance have no effect, while select-all will select all of the blocks in the workspace. Copy will copy the edit area of all selected boxes to the clipboard. And, finally, paste first checks to see if the clipboard contains valid scheme expressions then places each one in its own box, starting at the cursor, as if it were opening a file.
• Copy Block 
  Copies the current block to the clipboard including both the edit and evaluation areas.
• Remove Block 
  Removes the currently selected block from the workspace and makes the previous block the current.
• Remove All Blocks 
  Resets the workspace to a single, empty block.
• Insert Block 
  Inserts an empty block after the currently selected block and makes it current.
• Delete Global Def   
  Removes one or more global definitions from the Donkey environment. If any expression in a Donkey edit or evaluation area contains references to the variable, Donkey asks the user to confirm that the definition should be removed. If the user proceeds to remove the definition, evaluating the expression with the reference will result in an error of the form Reference to unbound symbol: <symbol> unless it is bound in the underlying environment or has been made primitive.
• Collect Local Defs 
  Removes all Local definitions from the Lifted Defs and Local menus (Sections 4.5 4.6) if they can no longer be accessed from the Donkey environment.
• Make Primitive  
  Similar to Load Primitive, evaluates the expression in the current block in Donkey's underlying environment. It also removes that block and if the expression defined a variable in Donkey's global scope, it is removed. This action may also be performed by executing (make-primitive <expr>)  where expr is the expression to be evaulated in the underlying environment.
• Preferences... 
  This menu item will let you set a number of preferences for using Donkey as well as other applications written for DrScheme (Section 7). See Section 4.3 for a discussion of Donkey's preferences.
