### using ctags with vim
# examples:
#   vim -t "Compiler"
#   vim -t "OPS.Get"
#   vim -c ":ts Platform.Read"
#
# when inside the editor you need to jump to the fully qualified tag, 
# not just procedure name e.g. when you have Platform.Write, you 
# can't just place cursor on W then <C-]> and expect it to resolve 
# correctly all the time.
# your better options are
#   autocmd FileType oberon setlocal iskeyword+=. 
#   autocmd FileType modula2 setlocal iskeyword+=. 
#   :ta Platform.Write
#   v 3e <C-]>
#   :ts Platform.Write
#   g <C-]>
