How do I cycle through my set Esnaps?

When an object is selected and several esnap options are active in esnap settings DraftSight (DS) does not always select the particular esnap that I want at the time.  Is there a way to quickly cycle through the other esnaps that are active (e.g. a button such as "Tab") ? or am I stuck with using esnap over-rides?

If there is not a quick way to do this then I would suggest it as a worthwhile enhancement to what I am finding is a very promising program.

The DS team is doing a stirling job!!!
