Cursor Language Indicator

Windows AutoHotkey Usability

Reflect keyboard layout changes in mouse pointer look.

Description

When typing in English cursors are default white. When switching to another keyboard layout the cursor turns black to remind you. The Windows language bar can be hidden (it wasn't near the typing anyway) and you can switch languages with Left Alt+Shift

Usage

Run with AutoHotkey.
Different versions of Windows may have different cursor paths/filenames. Make sure they match.

Reference

Adapted from code posted in these AutoHotkey forum threads :

If current keyboard layout is english then - AutoHotkey Community
How to change the cursor image? - AutoHotkey Community

To set up another default language look up its hexadecimal locale identifier here:
Language Identifier Constants and Strings (Windows)

⚠️ If you reset cursors by assigning an empty string some screen recording software may register it as only an empty outline!

Please apply this difference to the mouse pointer in the selected mode

One of the best self -hotkey script there is.
congratulations
