 @doc doc"""
 Holds information on what variables to alias
 when solving a LinearProblem. Conforms to the AbstractAliasSpecifier interface. 
-    `LinearAliasSpecifier(;alias_p = nothing, alias_f = nothing, alias_A = nothing, alias_b = nothing, alias = nothing)`
+    `LinearAliasSpecifier(; alias_A = nothing, alias_b = nothing, alias = nothing)`
 
 When a keyword argument is `nothing`, the default behaviour of the solver is used.
 
 ### Keywords
 
-* `alias_p::Union{Bool, Nothing}`
-* `alias_f::Union{Bool, Nothing}`
 * `alias_A::Union{Bool, Nothing}`: alias the `A` array.
 * `alias_b::Union{Bool, Nothing}`: alias the `b` array. 
 * `alias::Union{Bool, Nothing}`: sets all fields of the `LinearAliasSpecifier` to `alias`.
