Another list is in IDE/Help/Reference/Index.htm along with IDE/Help/language.html of the Beta 11 install, but again some commands are not yet documented (the list above is more comprehensive).
The "language" command list is separate from the "index of commands" for one reason or another, so it's not in the list above; those extra commands include:
#include
#constant
rem
remstart
remend
dim
do
exit
loop
end
if
else
elseif
endif
repeat
until
while
endwhile
for
step
next
goto
gosub
return
select
case
case default
endcase
endselect
function
exitfunction
