--- === ControlEscape ===
|
|
---
|
|
--- Adapted very loosely from https://github.com/jasonrudolph/ControlEscape.spoon
|
|
--- Removed timing/delay; always send Escape as well as Control
|
|
---
|
|
--- Make the `control` key more useful: If the `control` key is tapped, treat it
|
|
--- as the `escape` key. If the `control` key is held down and used in
|
|
--- combination with another key, then provide the normal `control` key
|
|
--- behavior.
