* may I point out that you're using "execute" when you don't need to.
* you're already in ex mode; no need to use colons to do ex mode commands
* ctrl-w_l can be performed with wincmd l .
* to perform normal mode commands in a function, use norm! (the
exclamation prevents any maps from interfering)

So, with these points in mind:

fun! TodoListMode()
  e ~/.todo.otl
  wincmd l
  norm! zMzr
  Calendar
endfun

Now, I confess that I didn't test this...

Thanks for the pointers!

I ended up with this, which doesn't use any normal commands at all ironically.


function! TodoListMode()
 e ~/.todo.otl
 Calendar
 wincmd l
 set foldlevel=1
endfunction

Thanks for the help though, it works just as one would hope now!

Hi fREW,

execute "normal! wl zM zr"

would be my guess, but I've never tried writing my own functions, this 
is adapted from someone else's work, so someone else's input would be 
useful :-)
