Change layer using numerical keyboard

 Hi all!!

Im Carmelo from italy and im a new user of this fabulous cad software!

Before to download and use this great software, i used another cad software where in my model file *dwt, i could change layer using numerical keyboard. For each number (from 0 to 9) corresponded one layer. For example, click 1 and i work with layer 1, click 2 and i work with layer 2.

For freeze all layer i clicked "Ctrl+L" and for unfreeze all layer i clicked "Alt+L".

Because i use many layer i need to have this configuration but i can not get it.

Could you help me?

Regards

Carmelo

ps: im sorry for my bad englishand compliment for DraftSight cad ;)
