" All IDE actions use :action <ID><CR> instead of <Action>(ID).
" Both are documented by IdeaVim but <Action>() in a mapping RHS

" sethandler — MUST be at top level before any mappings.
" IdeaVim processes these in a separate startup phase; putting
" them inside an if block causes them to be silently ignored,
" which makes C-h/C-l fire random IDE actions unpredictably.
