Never mind, I figured out "F". Funny that it isn't even
mentioned on the time series functions page.
I would agree that this information is not the easiest thing to find
if you aren't certain what you are looking for: -hsearch time series
operators- (in Stata 9.2 or later) returns -tsvarlist- as the second
link, while -hsearch time series functions- doesn't give -tsvarlist-
until the 78th entry on my machine -- long after most people would
give up searching, I suspect.
I have observed over time (small pun intended) that many people
think of L., F., D., and S. as functions instead of operators, and
thus have trouble tracking down the information they need. Note that
in -help time- it does say, "See -varlist- for a table of time-series
operators," but that sentence apparently is easy to miss. Perhaps an
explicit mention of -tsvarlist- under "Data management tools and time-
series operators" on the -help time- page would, well, help. A link
to -tsvarlist- in the Description paragraph of -help
time_series_operators- similarly might mitigate some of this
