Text Case Converting Keyboard Shortcuts

Setup/Preset Sharing
1

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!

Looks great, do you have something for Sentence case as well?

I'm new to BTT and love it but I thought I'd chime in as you've had no response from the OP. To add Sentence case, duplicate one of the hotkeys in the group, change the hotkey to one of your liking and change the transformer Javascript to this:

async function toSentenceCase() {
const clip = await get_clipboard_content({ asBase64: false });
const selection = (await get_selection({ asBase64: false })) || "";
const textToProcess = selection.trim().length > 0 ? selection : clip;

let result = textToProcess.toLowerCase();
result = result.replace(/(^\s*\w|[.!?]\s+\w)/g, (match) => {
return match.toUpperCase();
});
result = result.replace(/\bi\b/g, "I");

await paste_text({
text: result,
insert_by_pasting: true,
});

return "";
}

Don't forget to save it! That it :slight_smile:
