Learn the layout

Mon, 01 Jan 0001 00:00:00 +0000

Nobody memorizes 357 bindings up front. Capslock teaches the layout in three ways: it shows the current plane when you pause, it can show each action as it runs, and the Playground has short lessons that follow your own mappings.

Hold-to-Reveal

Hold Caps Lock without pressing another key. After a short delay the current plane appears on screen as a full keyboard with every action written on its key. Press ⌘, ⌥, ⌃ or ⇧ to switch planes while it is open; release Caps Lock to close it.

Coexisting with Karabiner-Elements

Mon, 01 Jan 0001 00:00:00 +0000

Capslock needs Caps Lock and the F18 key to itself. It never edits, disables, or uninstalls Karabiner-Elements or any other tool. When something else already uses those keys, Capslock refuses to start and tells you what to change.

What counts as a conflict

A system key remap of Caps Lock. If another tool has remapped Caps Lock, Diagnostics shows "Caps Lock is used by another tool".
Another use of F18. If anything remaps a key to or from F18, Diagnostics shows "F18 is already in use".
A Karabiner-Elements rule. When Karabiner-Elements is running, Capslock reads the selected profile and looks for rules that start from Caps Lock or F18, or that produce F18. It reports only how many it found, never their names or contents.

Karabiner-Elements can keep running for everything else. Only rules on Caps Lock and F18 conflict.
