I've found several web pages that talk about how to set case sensitivity in searches in Kate. However, what I actually see on my screen doesn't match any of those pages. Here's a screen shot in which I'm using the the search and replace plugin:
And here's a screenshot of using just the built-in search:
Neither of those options look like they provide anywhere to set the case sensitivity of the search.
I'm using Kate version 16.12.3 with the KDE framework 5.31.0. Please let me know if there's any other info I should provide.
Any help on finding those options would be much appreciated.
