This template and the other related templates listed below produce a series of links for a specified page that is generally, though not always, of the form:

Page (edit | talk | history | links | watch | logs)

The six links are:

editedit the page;
talk – access its talk page ;
history – access its edit history;
links – access the what links here feature;
watch – add the page to one's watchlist; and
log – access its logs.

The major difference between the templates is the namespace of the page to which it is applied.

{{subst:ln|Category|Stubs}} results (or resulted) in this code:

{{lx|1=:{{ucfirst:Category}}:|2={{ucfirst:Stubs}}|3=:Category talk|4=talk}}

Note the important colon in 1=:, unnecessary (?) for other Lx namespaces.
Substituting both Lx and Ucfirst finally arrived at (line breaks added manually):
