Curved arrow tracing validation (Capto)

irep

Hello. 
When tracing multiple points arrow, we have to double-click the last position to stop tracing. But… if we forgot to double click… there is no shortcut to do the same thing. We have to double-click "one step beyond"  and readjust the points. I thought that hitting, say, the enter key or esc or the return key, or space key or clicking back on the selection tool it would have stopped the tracing, but no. Could you add such a functionality ? Thank you.
