Get into a group and select a piece of the group without un-grouping it
Key cap configure perhaps is made of groups?
How to deal with each logical keycap layer having it’s own font?
Lets you move individual objects keeping them in their group
A group of groups of objects is a nest
Select one group, shift-click another group, now you can group those two groups
This seems to be one way to keep everything positioned correctly
Each time you click a nest it cycles through selecting all of the groups
Group logically related features as their own groups so that you can dig deeper and deeper as you would expect
Double-clicking objects in a nest access isolation groups which cycles through the nested groups
Either way when you are in a particular group, the edit menu operates on the objects in that group. So Edit → Select All selects everything in that group. Obvious but news to me.
Just noticed in the top area that it also shows the groups including the one that you are in right now
How long do groups live?
