Port of the touchcursor-linux project to macOS.
Icon by Gregor Cresnar
This application remaps the uiophjklnmy keys to different movement keys when the spacebar is pressed down, allowing you to keep your hands on the home row.
i - up
j - left
k - down
l - right
u - home
o - end
p - backspace
h - page up
n - page down
m - del
y - insert
In progress, but for now you may download this repository and build with XCode.
Martin Stone, Touch Cursor: wonderful project for cursor movement when coding.
- Create automator wrapper app
- add shell script that runs what is in 'setup.sh' script
- i added the executable to my sudo visudo path
- add automator wrapper app as login item
in sudo visudo

Checked with the CG Folks and apparently CGEventTap stops working when the system is in secure input mode. This can be enabled by any process and can stay 'stuck', preventing taps from ever coming through until you log out or restart the machine.
This is also confirmed by the author of karabiner elements https://github.com/pqrs-org/Karabiner-Elements/blob/main/docs/DEVELOPMENT.md#cgeventtapcreate
It's not fully working yet but I'm getting the callbacks now for when you tap a key. I just need to wire up the keycodes with the map I have

Owner Author cprovatas commented 27 days ago As I was implementing this, I discovered that there is an SPI called CGSSetSecureEventInput, that appears to toggle secure input mode. If this API actually works, then I wouldn't need to rewrite all of this using the IOKit APIs. I will investigate this first.

Owner Author cprovatas commented 14 days ago • That doesn't work^. Window server validates the connection id against the app the enabled secure input mode. Any app can't disable it.
@cprovatas
Owner Author cprovatas commented 14 days ago Explored using the Services API, which seems plausable. It essentially creates a menu item on every application calls some SPI called _NSSaveServiceActions. The only part thats unclear is if you can create these service actions programmatically
@cprovatas
Owner Author cprovatas commented 14 days ago CGSSetSymbolicHotKey might be usable

@cprovatas
Owner Author cprovatas commented 8 days ago Another method is to use HID Service Filters but I couldn't get that to work in Swift, also the debugging experience would be terrible running a plugin against the kernel
@cprovatas
Owner Author cprovatas commented 7 days ago • To detect if a connection is trusted– Skylight checks for presence of /var/db/.AccessibilitySecureTap file and if the process has the com.apple.private.accessibility.secureTap entitlement. I think also the kTCCServiceAccessibility entitlement. I confirmed this locally by using the Hot Key APIs
@cprovatas
Owner Author cprovatas commented yesterday CGSSetHotKey doesn't really work with just shift as the modifier key while in secure input mode. I also couldn't figure out how to filter input. Attempting to use a forked project instead
