tab-completion

[GopherAtl]

depends, partially, on code inspection (issue #5). Build and maintain a dictionary against which tab-completion can be used for local and global identifiers and table members. Use modified selected-text insertion, updating as you type, with tab to accept. Possibly extend to include syntax-based keyword suggestion - for "then," "do," and "end", plus things like closing brackets/braces/parens, though this extension should be togglable on/off in the menus.
