Although iRAPP does not currently support the mapping of Ctrl+Key combinations at this time, we are working to add this feature in an upcoming release this year.

In the meantime, one of our clients, Emmanuel H. (@ehuna), shared with us the following workaround:

"I was able to get the key mappings working by running http://www.autohotkey.com on my Windows 7 machine.  This allowed me to map for example CTRL-C to COMMAND-C - so I can use CTRL-C on both Windows apps or Mac apps (like XCode) running through iRAPP.

Makes the integration of the Mac apps running on Windows even more seamless!  I know this is a feature you're working on and I'd prefer to have it built-in into iRAPP - but this is something else that your users might enjoy.

(Note: I first tried to run this cool utility http://pqrs.org/macosx/keyremap4macbook/index.html on the Mac itself - it even has a "For PC Users" section.  Unfortunately, although the mappings did work on the Mac keyboard itself, they did not work through iRAPP, VNC, or RDP.  I had to install AutoHotKey on the windows machine to get it working)."

Below are the most common commands Emmanuel found useful when working with Mac apps blended on his Windows machine:

#IfWinActive ahk_class RAPWndWindowClass
; copy, paste, and cut
^c:: Send, #c
^v:: Send, #v
^x:: Send, #x
; undo
^z:: Send, #z
; select all
^a:: Send, #a
; find
^f:: Send, #f
; save file(s)
^s:: Send, #s
; cursor navigation
Home::Send #{Left}
End::Send #{Right}
^Left::Send !{Left}
^Right::Send !{Right}
#IfWinActive

Thanks again Emmanuel for sharing!  If you have discovered solutions that we should know about, please let us know: support@coderebel.com.
