Virtual Cmd key for iPad Standard Keyboard

I normally always use an external keyboard, but mine just died, and it will take a few days to get a new one delivered.
This is the first time I use the on-screen keyboard, what I really miss is a quick way to do cut-paste. Some terminal apps like Blink have a virtual Alt key, would it be possible to in a similar fashion have an Cmd key, to speed up cut paste? Doing it by fiddling on the screen iOS style is far from practical if you do code refactoring etc
