In Windows operation systems it is a common way to use Control+Insert keys instead of Control+C to copy selected text.
This is necessary to support left-mouse-handed people and it's driving me crazy that it does not work within your product(s).
At least I would love to use this option when working within the Comparison to copy code from a left or right script using Ctrl+Ins.
For completeness you should also keep "Shift+Insert" for Paste and "Shift+Del" for Cut operations in mind.
Thank you
