<+-> sets the stepping environment until the end of the
To easily let two items show themselves together do:
. tells the item, to not increment the slide counter.
This works fine for single items, however, if you use nested levels like this:
you will find that
1 -- 10 are shown together. This is probably not what you want. For tweaking there is an optional argument to the counter argument
# is a number. If you specify
<.(1)-> it will be equivalent to adding
1 to the slide where it will be shown. Hence the trick is to step the counter and force it to not increment:
The second pause is a local step counter. One would think you can use it instead of the
(1) notation, however the nested list complicates things and the above method is more lenient.
