Hi Mark, thanks for reply, the No's I am referring to start at top 5 and finish at bottom -75 to the right hand side of vertical cursor in tx mode
tried toggling on the show additional and no did not change anything.

Being a relative new operator to thetis only 2 years I am trying to establish how to toggle on the numbers beside the cursor when in TX mode to enable me to see what my IMD levels are, please see attached jpeg from a friends screenshot. Any assistance greatly appreciated. I am using Thetis 2.10.3.6X...
