What's the difference between *clearmark and hm_markclear command?

Hello all,

What's the difference between *clearmark and hm_markclear command? It seems that both command are used to clear entities on specified mark. From the help manual.

 

   

 

hm_markclear command has an optional about 'panel_sensitive'. However, from the manual, I don't think I have understood the meaning of this option and when to use it. Is there any example to explain this?

 

Thank you

Roy
