isabelle - Can I define multiple names for a theorem? -

suppose have theorem:

theorem non_ascii_thm_name:   "true"   simp 

i want define ascii name non_ascii_thm_name notation command. example, this:

notation non_ascii_thm_name ("ascii_thm_name") 

the isar commands notation , abbreviation can used constants. there isar command allows me to this?

preferably, want isar command provide synonym. example, if use sledgehammer, preferable there exist 1 theorem, non_ascii_thm_name, sledgehammer not using additional fact ascii_thm_name.

a partial solution use command:

lemmas ascii_thm_name = non_ascii_thm_name 

this define new theorem called ascii_thm_name same non_ascii_thm_name.

there unfortunately no guarantee tools such find_theorems use new name, instead use own heuristics determining "best" name output user.

an alternative synonym lemmas theorems, though former considered more standard approach.
