It's a simple script to emulate arrow keys using CapsLock. Navigation is done like in vim standard mode.
Navigation:
CapsLock + j: Down arrow
CapsLock + k: Up arrow
CapsLock + h: Left arrow
CapsLock + l: Right arrow
Text selection:
CapsLock + Left Alt + j: same as Shift + Down arrow
CapsLock + Left Alt + k: same as Shift + Up arrow
CapsLock + Left Alt + h: same as Shift + Left arrow
CapsLock + Left Alt + l: same as Shift + Right arrow
You can use the script by loading it in your AutoHotkey installation or by running the script copmiled to standalone .exe. To compile, sipmly run:
build.bat
The motivation behind this tool is to emulate arrow keys quickly. These keys are used almost everywhere: context menus, drop-downs, spin-buttons etc. There's no need to emulate vim mode in text editors because every advanced text editor supports vim mode (build-in or by using plugins).
While it's not about emulating vim mode in text editor, it could be useful to use some of vim commands in simple input fields. These are not yet implemented, but I highly encourage you to create pull request.
