--note that this prefix macro code: 
elsif equal(macro, "il") then 
       shell("eushroud " & file_name) 
	normal_video() 
	goto_line(0, b_col)  -- refresh screen 
 
-- does the same thing as this code: 
elsif equal(macrol, "il") then 
      add_queue(ESCAPE & "d" & " eushroud " & file_name & CR) 
 
-- and this code: 
    elsif equal(macro,"il") then    -- shroud the current file  
	shell("eushroud " & file_name)  
	add_queue(CONTROL_B & CONTROL_T)          
 
------------------------------------------------------------- 
 
-- if you choose to add a hot-key shell command   
-- to the get-escape elsif clauses, to execute a shell command 
-- you can avoid adding the calling command letter to the list  
-- of hot-keys by choosing the second method above: 
 
    elsif command[1] = 'S' then 
      add_queue(ESCAPE & "d" & " eushroud " & file_name & CR)  -- note the final CR 
 
-- one advantage of using a prefix-macro instead of ESCAPE + hotkey 
-- is that the prefix macro calling command or label can be multiple letters 
-- allowing for a more "readable" or easy to remember mnemonic code: 
--   ;il may be easier to associate with shroud than the "S".  
 
-- perhaps a better example - in my original post for multi-line quotes 
-- I chose the prefix macro latel "bt" for back- tick, but "mlq" might be easier to remember: 
 
     elsif equal(macro, "mlq") then  -- called by entering ";mlq ", 5 keystrokes                                                            
	add_queue("` `" & repeat(ARROW_LEFT,2)) 
 
-- on the other hand, you can assign a symbol as an ESCAPE hot-key 
-- such as: 
 
   elsif command [1] = '^' then  -- '^' will not have to be added to the list of hot-keys 
   add_queue(ESCAPE & "d" & " eushroud " & file_name & CR)  -- because of the final CR. 
 
------------------------------------------------ 
 
-- Prefix macro's allow you to use multiple mnemoinic calling characters.  
-- ESCAPE hot-keys are limited to one character or symbol.  
-- In addition to being easier to remember, prefix macros  
-- allow you to keep your fingers closer to the home-keys.  
 
-- ESCAPE hot-keys are somewhat constrained to a fix number of single letters or symbols. 
-- However, you can add additional menu's which would allow you to re-use letter or symbols, 
-- but that would involve more key-strokes. 
 
-- Prefix macros are very good to use to save key strokes 
-- when entering longer commands which are used frequently: 
 
   elsif equal(macro,"ri") then                                                               
        add_queue("routine_id(\"\")" & repeat(ARROW_LEFT,2))  
    
   elsif equal(macro,"pf") then                                                               
        add_queue("printf(STDOUT,\"\", )" & repeat(ARROW_LEFT,4)) 
---------------------------------------------------------------- 
 
-- this little prefix macro might be useful if you have a  
-- long string of code which extends beyond the width of your screen.  
-- It basically executes a CR at the beginning of the last word within  
-- the width of the screen: 
 
    elsif equal(macro,"rm") then                                                               
        -- cuts right margin to format long lines                                        
        add_queue(HOME & repeat(ARROW_RIGHT, screen_width) & CONTROL_L & CR)
