TeXShop

• In a document with over a thousand pages, the PageNumber box in the toolbar displays the number with a comma, as in 1,325. But users who want to go to a different page must enter the new page number without a comma. This makes it impossible to edit the existing number, say by changing 25 to 17 to go to page 1,317. This is fixed.
• Suppose a document has several pages of preliminary material before the main text begins. Perhaps these preliminary pages are numbered i, ii, iii, iv, v, ... and the main pages are numbered 1, 2, 3, 4, 5, ... Then entries in the PageNumber box will not be in sync with the actual page numbers in the text. The previous version of TeXShop introduced a fix for this problem, which required the user to insert a magic comment line and manually indicate the number of preliminary pages. The fix then numbered the preliminary pages 1#, 2#, 3#, ... and the main pages 1, 2, 3, ... Moreover, users could enter a number like 17 in the box to go to main page 17, and 2# in the box to go to the second preliminary page.
• TeXShop users need to find a way to remember these additional lines. Some may add items to the Macro menu, while others may modify their templates. It is also possible to add appropriate items to the Command Completion dictionary.
• After these lines have been added to the source, it is necessary to typeset to see changes in the PageNumber box. A lot of effort has gone into modifying the PageNumber whenever appropriate information is available in the log file. When TeXShop opens a new document, it checks to see if a log file is present, and if so it reads the log file to adjust the PageNumber box. If TeXShop is closed while documents are open, the documents will reappear the next time TeXShop starts with correct PageNumber entries.
