To help you differentiate between locked and unlocked layers, you can do the
following:
Hover over an object to see whether a lock icon is displayed
Dim the objects on locked layers
NOTE Grips are not displayed on objects that are on locked layers.
Select Objects by Properties
Use object properties or object types to include objects in a selection set, or
to exclude them.
To quickly define a selection set based on specified filtering criteria, use
Select Similar (SELECTSIMILAR) to select similar objects of the same type
based on specified matching properties
AutoLISP function SSGET to create a custom selection filter
With object selection filters, to filter your selection set based on color, linetype,
or lineweight, consider whether these properties are set to BYLAYER for any
objects in your drawing. For example, an object may appear red because its
color is set to BYLAYER and the layer color is red.
By default, objects of the same type are considered similar if they are on the
same layer, and, for blocks and other referenced objects, have the same name.
Subobjects are only considered at the object level. For example, when a mesh
vertex is selected, SELECTSIMILAR selects other mesh objects, not just the
mesh vertices.

selected objects are displayed.
For commands that use the Select Objects prompt, you can
Enter a command first, and then select objects
