if any layer or group or object is "active" that is the light blue highlight color is showing over that item in the layers panel, we are able to use the "options for selection" command from the layers panel menu.
If I draw any object and "active" it by clicking on it in the panel, the "options for " gets active (the "options for selection" greys out for no active item). then clicking for the options pops out a window with several options for that item.
For an object, the pop out window only shows three options that is name, show and lock. if I check the lock then in the edit column the lock icon appears for the item.
My question arises when clicking the object and activating it from the layers panel, doesn't let us use the "Object>Lock>Selection" command as if I click and drag over the object only then am able to use "Object>Lock>Selection" although the result is the same using these two different methods ("options for selection-> lock" vs. "Object>Lock>Selection") showing the lock icon in the edit column beside the object thumbnail.
What is the difference between click and drag over the object to select it vs. click the object thumbnail from the layers panel?
And what does it mean by selecting object and activating layer or group or object?
