Shallow display of a list:

Shallow display of a nested list:

Shallow[expr] formats as expr truncated to depth 4:

Compare with:

Shallow[expr] prints parts of expr after the 10 part in skeleton form:

Truncate expr to an effective depth of 3:

Print parts of expr after the 5 part in skeleton form:

Print parts of expr below depth 3 or after the 5 part in skeleton form:

Print all lists in expr in skeleton form:

Shallow[expr,{d,l},form] prints parts below depth d, after the part l or matching form in skeleton form:

Shortened outputs contain Skeleton objects:

Shallow[expr] is equivalent to Shallow[expr,{4,10}]:

Short displays with long expressions shortened from within:

Shallow shortens from the end:

When an input evaluates to Shallow[expr], Shallow does not appear in the output:

Out is assigned the result Range[50], not Short[Range[50]]:

The output of Shallow cannot be used as input if k appears in the result:

Copy the output and paste it into an input cell. The 90 will cause an error:

Even when an output omits Shallow from the top level, it is not stripped from subexpressions:

The output does not have Shallow in it:

However, the variable e does have Shallow in it, which may affect subsequent evaluations:

This Join is not evaluated due to the intervening Shallow:

Assign variables first and then apply Shallow to the result to maintain computability:
