[texshop] ⌘T to main

[Sean Bethard]

Fantastic! That works great, thank you. Exactly what I was looking for.

Also thanks for the tip about syncing with Cmd-Click. That's an
incredible feature I didn't know about.

The second line above tells TeX to typeset chapter two only, speeding up typesetting while chapter two is being written. When the book is complete, this line can be commented out and the entire book can be typeset a final time.

But after changes are made to this input file, TeXShop should not typeset two.tex; instead it should typeset the root file. TeXShop can be told to do so as follows. Indicate the root file in one of the first twenty lines of each chapter file by writing

In the above example, the various chapters are contained in subfolders within the folder containing the root file. In that case, you could enter ../Main.tex in the first source line or dialog window, showing the location of the root file relative to the chapter input file.

Since a preview window may correspond to several source windows, command-1 will activate the source window which previously activated the preview window, or the root source if no previous command-1 was entered.

This method will continue to be supported in the future, but should not be used because the "% !TEX root = ..." method is more robust. Consequently, the "Set Project Root..." command has been removed from TeXShop menus. When the "Set Project Root.." command was used to indicate a root file, TeXShop remembered the name of the root file by writing the information to a file with the same name as the input file and the extension ".texshop". For instance, if the input for chapter two was in two.tex, TeXShop wrote the name of the root in two.texshop in the same directory as two.tex. If the file two.texshop was later thrown away, TeXShop would revert to typesetting two.tex rather than Main.tex.
