Ctrl+Ins shortcut on Mac

Recent Macs notoriously lack an "Insert" key, so the "Ctrl+Ins" shortcut to copy the source content of the current segment to the target area is basically impossible to type without convoluted workarounds. In Trados Studio one can simply remap keyboard shortcuts, but this function isn't available in Trados Live. Is there any chance of implementing key remapping or introducing alternative shortcuts that can actually be typed on a Mac?
