I put together a set of text-transformation shortcuts for BTT using the “Transform & Replace Selected Text with JavaScript” action. The goal was to create a super-fast workflow for developers, writers, and anyone who edits text all day. I’m currently using ⌃⌥⌘ + letter, shortcuts don’t conflict with any common macOS or app defaults, so they work reliably everywhere. I no longer have a touch bar, but these could easily by modified to work with a set of touch buttons or a floating menu.
text_case_converters.bttpreset (18.1 KB)
This preset lets you select any text and convert it into:
• ⌃⌥⌘U → UPPERCASE
• ⌃⌥⌘L → lowercase
• ⌃⌥⌘T → Title Case
• ⌃⌥⌘C → camelCase
• ⌃⌥⌘P → PascalCase
• ⌃⌥⌘S → snake_case
• ⌃⌥⌘K → kebab-case
• ⌃⌥⌘[SPACEBAR] → Special-characters → spaces
• ⌃⌥⌘- → Special-characters → dashes (-)
• ⌃⌥⌘_ (aka ⌃⌥⌘SHIFT-) → Special-characters → underscores (_)
Each transformation runs through a small JavaScript snippet inside BTT and replaces the original selection automatically — no clipboard juggling, no external apps.
Enjoy!
