Include a Macro
The <Include> button on the Edit Macro window allows you to include macro data stored in a text file at the time your macro executes. For example lets say you have a macro that types "Billy Button bought a biscuit"
And you create a file called C:\MYFOLDER\MYMACRO.TXT that contains the phrase "a broken buttered ".
Now if you insert the cursor between before the word "biscuit" in the macro and clicked the <Include> button and chose the file C:\MYFOLDER\MYMACRO.TXT, the phrase "Billy Button bought a broken buttered biscuit" would be typed.
This is handy when your macro data may change from time to time but you don't want to rewrite your macro.
