Tap for Escape
Tap Caps Lock on its own and it sends Escape, for leaving insert mode or closing dialogs.
Make Caps Lock great again.
Tap it for Escape. Hold it for Hyper. Add ⌘ ⌥ ⌃ ⇧ to reach sixteen control planes for the cursor, editing, windows, apps and the mouse, without leaving the home row.

Questions
Before you install
Do I need Karabiner-Elements?
No. Capslock builds the layout in. Karabiner-Elements can keep running for other keys, as long as none of its rules uses Caps Lock or F18.
Does it record what I type?
No. Keys are handled in memory on your Mac. Capslock has no analytics and sends nothing anywhere; the Statistics page keeps only counts.
Can I still type capitals?
Yes. Hold Caps Lock and press Escape to turn real Caps Lock on or off.
When can I download it?
Capslock 0.4.0 is a release candidate. A signed, notarized download will appear on the Download page once it passes final acceptance.
