In the case of untitled documents, the temporary copy will be in the system-designated temporary items location, which is arbitrary but generally not anywhere near $HOME. When using 'Check Syntax' or 'Run' on an unsaved or untitled document, the application will now write out a temporary copy of the document.Differences that have been applied are now crossed out in the Differences window list, in order to avoid janky font italicizing effects on some OS versions.Added Command-K and Command-R as keyboard equivalents for 'Check Syntax' and 'Run', respectively.Most will use the specified size, except in specific cases where circumstance requires the use of a fixed font size. Lists in the application all use the system font. The 'List Display Font' setting in the Appearance preferences has been replaced with a slider to set the font size.For convenience you can assign keyboard equivalents to these commands in the 'Menus & Shortcuts' preferences. Use these to change the magnification of the text in editing views. On the 'Text Display' submenu of the View menu, there are three new commands: 'Zoom In', 'Zoom Out', and 'Actual Size'.
