harrrrrry so this is what I did...
Typed in "help" selected text pressed ctrl c, deleted then ctrl v pasted then ctrl z and did what supposed to do "undo" ctrl z is not to delete from clipboard it is to undo last operation. So if last operation was copying to clipboard then ctrl z would delete
Sorry if a bit long winded, that's just me.
And if anyone wants to do this on an android phone then I would recommend "Hacker's Keyboard" from play store.
