How would one write a function that one could bind to, say, SUPER-f, which inserts the code:
for () {
}
in the buffer with my cursor being moved into the () parens for filling out the loop guard?

What did you try?– asjoFeb 28, 2016 at 17:52

Didn't try much of anything, since my knowledge of emacs is limited to what's builtin. However, I had not heard of yasnippet and it seems to do the trick.– eofFeb 28, 2016 at 18:35

@eof: if yasnippet solved your problem, please post an answer to your own question that details the solution, and accept it.– Dan ♦Feb 29, 2016 at 0:08

I think I'd do it like this:
(define-skeleton my-for-statement
"Insert a for () {...} skeleton."
nil
\n "for () {" \n > _ "}" \n)
The \n are for "newlines" (and the ones at beg/end are only added if needed). The _ basically says that if you have selected a region before running the command, then this region will end up right where _ is (IOW, the region will be wrapped by the "for" statement). And the > in front causes this region (if any) to be re-indented.
You can then do M-x my-for-statement and that will insert the statement.
