- Holding down the option key while selecting the Typeset menu, or holding down option-command-T, erases aux files and then typesets. This behavior has been extended to the Typeset icon in the toolbar; holding down the option key and clicking this icon now erases aux files and then typesets.
- The tab menu in the toolbar lists the beginnings of chapters, sections, subsections, and so forth; selecting an item in this menu takes you to the corresponding spot in the source file. This menu is supposed to be updated as the user edits the source file. Curiously, a bug prevented this update if the toolbar was in "Text Only" mode. This bug went unreported for perhaps twenty years. Now it is fixed.
TeXShop has a preference setting which creates a Tags menu in the main menu bar, duplicating the Tags menu in the toolbar. The bug also affected this menu bar item. I am unable to fix this second bug without risking performance issues for the editor. However, if both tags menus are visible and the menu bar version becomes out of date, using the toolbar version once will update both versions.
