I haven't used ACAD since 2000 but, try this. It may do what you want.
Type SETENSELMODE in command line.
0 ungroups and 1 regroups.
It doesn't hide anything, so if that is what you're looking for, this command isn't it.

Hi Sylvia,

That's exactly what I was after!! Thank you!

SETENTSELMODE

0 Does not select Groups or associative Hatches
1 Selects Groups
2 Selects associative Hatches
3 Selects Groups and associative Hatches

See thread 1480-375989. It describes how to create a button that will enter the command, instead of typing it all the time, or perhaps you have a programmable keyboard or mouse.

Seen that post you did, had it bookmarked!

I have two extra buttons now to set the SETENTSELMODE to one or zero.

I did have a go at changing these macros that toggle settings but couldn't crack it! Don't know enough about Diesel.

^P'orthomode $M=$(if,$(and,$(getvar,EnblOrtho),1),$(-,$(getvar,EnblOrtho),1),$(+,$(getvar,EnblOrtho),1))

^P$M=$(if,$(and,$(getvar,SetESnpMode),16384),'osmode $(-,$(getvar,SetESnpMode),16384) )$(if,$(eq,$(getvar,osnapoverride),0),'osnapoverride 1)

Tried to do something like this,
^P'SETENTSELMODE $M=$(if,$(and,$(getvar,SETENTSELMODE),1),$(-,$(getvar,SETENTSELMODE),1),$(+,$(getvar,SETENTSELMODE),1))
but I can't get it to work.

HA!

Just did it!!!!!!!!!!!!!!!!

That last one works!!!!!!!!

Must have not done something before, SORTED!!!

I'm SO happy right now!

I've made a new shortcut key, CTRL=H, and the groups toggle on and off like in AutoCAD now!!!! YAY!
