In multi level numbering, how can I revert to a higher level without a
separate number without affecting the lower level.

Example: In the following sequence:

1) line 1
2) line 2
a. line 3
b. line 4

I want to achieve after line 4:

1) line 1
2) line 2
a. line 3
b. line 4
xxx

so that XXX relates to 2) and not b. but is not numbered.

If I go shift enter after line 4, I move to the next line without a number
but if I then go shift tab at that point b. goes to the higher level and
becomes 3) line 4 and decreases the indentation accordingly.
