About Just in Case
Just in Case converts selected text without leaving the page.
Select text, right-click, and choose one of three conversions:
- UPPERCASE, for headings
- lowercase, for email addresses
- AP Style Title Case, for article titles
AP Style capitalizes the first and last word and any word of four or more letters. Short articles, conjunctions, and prepositions stay lowercase in the middle (a, an, the, and, but, or, to, of, in). A word after a colon or dash is capitalized.
The extension replaces the selection in a text field or editable area. Undo works with the usual keyboard shortcut. If a page will not allow the text to be edited, the converted text is copied instead.
Shortcuts, which you can change in chrome://extensions/shortcuts: Alt+Shift+U, Alt+Shift+L, and Alt+Shift+T.
Conversion happens on your device. Nothing you select is uploaded.
