How do I suppress an unwanted 'return' character after very simple AHK (AutoHotKey) macro?

问题

I've redefined all the keys on the numeric keypad to automate programming tasks, including 'cut, 'paste' and 'copy'. But this macro ('paste') fails:

;=====  NumpadDot or  NumpadDel paste 
NumpadDot::
NumpadDel::
  Send,^v
Return

Surprisingly this sends a control-v but followed (slightly later) by a 'return/enter' keystroke. What causes AHK to send an extra keystroke and how do I prevent it? – None of my other macros have any problems.

回答1:

Finally discover the issue. I had comments before each macro like this:

;=====  NumpadPgDn  3 / NumpadPgDn  paste 
Numpad3::
NumpadPgDn::
SetKeyDelay (150)
 Send,^v
Return
;===== Numpad0 / NumpadIns  to Copy
Numpad0::
NumpadIns::
  Send,^c
Return

Unfortunately in one of the comments I had a ':' (colon) in place of a ';' (semicolon). This alters the behavior of the preceding macro in the file and adds a enter keystroke after its execution.
