Can anyone help me? Designing with AutoCAD for 16 years, but never done this...

Whoa. How is that I've never seen anything that simple?

Are there sites that give out these codes... where you can grab them and apply them to your drawing. This is wild.

It would likely be an eyeopener for you to try the ALIASEDIT command, where, if you haven't done it previously you can customize all of your SHORTCALLS (command aliases).
Set them so they make sense to you, it is your workspace after all.
The life (time) you save may be your own!

If you have LT, the following macro works - "_Change P la 0;;" - I have it assigned to CTRL+ALT+NUMPAD0.
I have CTRL+NUMPAD0 set to "^C^C-layer m 0;;" which makes the current layer 0.

Should this be "^C^C-layer m 0;;" "^C^C-layer s 0;;" s for set rather than m "make" implies a new layer to be created Autocad doesn't return an error luckily using m. 2014 ?

BigGal, you're probably correct, but the routine has worked from LT 2004 - 2013 (if it ain't broke, don't fix it!).
