When you initiate a Tool Change, the number of the tool is displayed in the Tool Number display - but I think you know that - are you asking how you get additional information out of the tool table - so that you can , perhaps display it, and choose the correct tool, without having to write the information elsewhere - or do you want the name of the tool displayed on the screen so you can put the correct tool in.
I have my tools in a box in number order - all in quick change holders - so on a tool change M6 the machine stops, moves to a suitable location, and displays the new tool number. It waits until I change the tool, then carries on.
It would be possible to display more information, if the information from the discription box is easily recoverable from the Tool Table. Quite clearly all the offsets are - I don't know about the discription.
