This Hammerspoon module provides quick case conversions for arbitrary text. Supported modes include:
- All lower case
- All upper case

- URL slug (adapted from Draco Blue)
Trigger with hotkey ⌃⌥⌘T. Once you type or paste text conversions for each supported mode will auto-populate. They can be chosen with ⌘1-4 or by pressing the arrow keys and then Enter. The text will be copied to your clipboard.
