I have a large job for a client who uses antique computers. They are so old that he can't run Lightroom. As a workaround, I posted the images I wanted him to look at on SmugMug and we had a disaster. Their sequencing on screen does not match my "as shot" sorting on my Lightroom (4). Is there a way I can print sequential serial numbers/ids on my images before I upload them to SmugMug so we are always talking about the same image?

You can change the numbers in the list by restarting the sequence or by specifying a new start number. You can change the list's style. You can do anything to this list that you can do to a normal numbered list because it is a numbered list, with one exception: the list, while easy to format, is fixed. If you delete an item, the list updates accordingly, but I haven't found a way to add numbers.

For the calendar job, I've used two master layers and four local layers. To create a master layer, click the New Master Layer (all pages) button at the bottom of the Object Manager docker. Objects placed on this master layer will appear on all pages of your design. Then, create the required number of regular or local layers (in this case, four) by clicking the New Layer button. You now have one page ready.
Instead of working harder than you need to, insert a one-column table with as many rows as necessary to accommodate your list. Then, using Word's numbering feature, number that column. Finally, convert the table to text. The resulting list is a fixed numbered list, so you'll have to live with its limitations; when you can do so, this method definitely beats most alternative solutions.

Yes it can be used for other documents. I use it as a basis to generate addressed letters to clients etc. Potentially you could use it with Access, but you’d have to set it up as a Mail-Merge document – but it would take a bit of fiddling around to get both mail-merge and the sequential numbering to work at the same time. it’s a matter of experimenting – I don’t have any other suggestions – it’s up to you to adapt it to your own needs. sequential numbering using word
