Allow user re-mapping of control shift (show reclaim) function

Hi

Can we please allow user re-mapping of control shift (show reclaim) function?
Dont see an option in F1 menu for this anywhere. Looks to be hard coded to control shift

Currently when you press control shift you see on screen reclaim (which is great)
However if you try to remap any other orders/commands which will utilise control shift + other key combo you invoke the reclaim on screen while executing the command, this results in a little bit of lag while executing the command as the reclaim is drawn
Other option currently is to avoid mapping anything with control shift in the command, but this limits the keys available to the user

many thanks if possible
