I agree about auto-complete, but already the editor Brief for MS-DOS, at least some 35 years ago, allowed you to define arbitrary templates for auto-completion.

I agree about auto-complete, but already the editor Brief for MS-DOS, at least some 35 years ago, allowed you to define arbitrary templates for auto-completion. For example, when writing a C program you could choose to have "f<TAB>" expanded to "for (=; <=; ++) {<LF><TAB>;<LF>}<LF>" or whatever indentation you preferred. There are many modern programming editors that allow a similar customization, though unfortunately for many of them this requires a more complicated procedure than in the far past. For any programming language with a verbose syntax, I consider necessary to take your time and define in your editor templates that would allow the fast writing of any program structure with a minimum number of key presses.
