AHK script to add words to a dictionary text file

Sometimes it may come handy to add words to a dictionary, in this case a tab-delimited file, without opening the file and writing the term and the definition. This script works by selecting the term, pressing the Windows+W key, adding the definition at the end of the input box and pressing enter or confirming with the mouse. The script adds the word pair to a file called "dict.txt" and saves and closes the dictionary file. The dictionary file must be in ANSI format.

#w::  ; Win+H hotkey
; Get the text currently selected. The clipboard is used instead of
; "ControlGet Selected" because it works in a greater variety of editors
; (namely word processors).  Save the current clipboard contents to be
; restored later. Although this handles only plain text, it seems better
; than nothing:
AutoTrim Off  ; Retain any leading and trailing whitespace on the clipboard.
ClipboardOld = %ClipboardAll%
Clipboard =  ; Must start off blank for detection to work.
Send ^c
ClipWait 1
if ErrorLevel  ; ClipWait timed out.
    return
; Replace CRLF and/or LF with `n for use in a "send-raw" hotstring:
; The same is done for any other characters that might otherwise be a problem in raw mode:
StringReplace, Hotstring, Clipboard, ``, ````, All  ; Do this replacement first to avoid interfering with the others below.
StringReplace, Hotstring, Hotstring, `r`n, ``r, All  ; Using `r works better than `n in MS Word, etc.
StringReplace, Hotstring, Hotstring, `n, ``r, All
StringReplace, Hotstring, Hotstring, %A_Tab%, ``t, All
StringReplace, Hotstring, Hotstring, `;, ```;, All
Clipboard = %ClipboardOld%  ; Restore previous contents of clipboard.
; This will move the InputBox's caret to a more friendly position:
SetTimer, MoveCaret, 10
; Show the InputBox, providing the default hotstring:
InputBox, Hotstring, New Definition, Type your definitin at the indicated insertion point.,,,,,,,, %Hotstring%`t
if ErrorLevel  ; The user pressed Cancel.
    return
IfInString, Hotstring, :R`:::
{
    MsgBox You didn't provide an abbreviation. The hotstring has not been added.
    return
}
; Otherwise, add the hotstring and reload the script:
FileAppend, `n%Hotstring%, dict.txt  ; Put a `n at the beginning in case file lacks a blank line at its end.
Reload
Sleep 200 ; If successful, the reload will close this instance during the Sleep, so the line below will never be reached.
MsgBox, 4,, The hotstring just added appears to be improperly formatted.  Would you like to open the script for editing? Note that the bad hotstring is at the bottom of the  script.
IfMsgBox, Yes, Edit
return

MoveCaret:
IfWinNotActive, New Hotstring
Send {End}
return
; Otherwise, move the InputBox's insertion point to where the user will type the abbreviation.
Send {Home}{Right 3}
SetTimer, MoveCaret, Off
return
