I foolishly updated TeXShop recently and I now have the following problem.

Previously, I could highlight text in the editor with the cursor and start typing to overwrite it. Now if I highlight some text to replace "abc" and I start typing something that requires holding shift down, such as "$def...", I end up with "$abc$def...". In other words, the highlighted text is enclosed with $...$ and then the rest of the text is inserted directly afterwards.

How can I get back to the previous setting of simply overwriting the highlighted text?

Got to the Editor tab of TeXShop->Preferences and uncheck Editor Can Add Brackets at the bottom of the Editor section of that pane.

  • By the way, it has nothing to do with the Shift key but rather with delimiters that are generated in pairs when there is a selection of 3 or more characters; i.e., typing $ with that selection automatically surrounded the selection with a matching set of $. – Herb Schulz Oct 29 '18 at 16:31
