There's an Emacs extension for Ada, that seems to be quite extensive,
including syntax completion (you type the "if", the editor the
"then ... end if") and syntax high-lighting. If I'm correct there
would also be cross-reference capabilities, so you'd be able to click on a
identifier and see where it's declared.
