Simple Before/After Script (Using AutoIt)

I've been using Capture One for about a year now, having moved from lightroom. Whilst c1 is a better product, there are a few features I miss, one of them being the easy before/after toggle lr has using the \ key, so I wrote a script to accomplish the same thing. I thought I'd post it here in case anyone else finds it useful.

#include <Misc.au3>

Local $tvHandle = 0

while True
$tvHandle = WinWaitActive("Capture One")
if Not ($tvHandle = 0) Then
WinActive("Capture One")
If _IsPressed("DC") Then
Send("{CTRLDOWN}r{CTRLUP}") ; CTRL+R
Do
Until Not _IsPressed("DC")
Send("{CTRLDOWN}z{CTRLUP}") ; CTRL+Z
Endif
EndIf
WEnd
It works with the free program AutoIt; you have to save the above code as a text file with the extension .au3 and run it (I've put it in my windows startup folder so it's always running). All it does is check if capture one is the active window, and if so, if you're pressing the \ key on your keyboard. If so, it sends ctrl+r to c1 (revert changes), and waits until you release \ again, at which point it sends ctrl+z (undo). It's not completely seamless as on my computer it takes c1 a second to perform the revert changes command, but for me it just makes life a little easier.
