# NOTE Oberon-2 receiver procedures not supported
### using ctags with vim
# examples:
# vim -t "Compiler"
# vim -t "OPS.Get"
# vim -c ":ts Platform.Read"
#
# you need to jump to the fully qualified name, since procedure names alone
# sometimes resolve to an incorrect module. that is to say putting cursor on
# W in Platform.Write and jumping will probably not work as expected, so you
# might have to do some of these
# autocmd FileType oberon,modula2 setlocal iskeyword+=.
# select the name fully
# v 3e <C-]>
# :ta Platform.Write
# resolve ambiguities interactively
# :ts Write
# g <C-]>
