[NTG-context] Start an itemized list with a given number

Hello everybody and thanks in advance for your advice, I’m unable to find in the documentation and in the wiki the way to start an itemized list with a number different from 1, for instance with 3. What I want to achieve is something like: Insert the key Try to turn the key If key is working 3. Open the door If key is not working 3. Change key 4. Goto step 1 So what is the way to start the list after « If key is not working » with the number 3 ? Eric Gerard
