Master Palette -> Symbols : What is the purpose of the check box 'System flag'
In the Master palette -> Symbols It is a check box named 'System flag'
I do not see any effect of checking or unchecking the box.
Tried in 3.0.5 but also in 2.3.2
Also not find info in the Hanbook v3 and v2
What is the purpose of this check box ?
Thanks in advance
