// quick answer
AltGr is sent as Left Ctrl + Right Alt, so remapping Ctrl or Alt in Keyboard Manager breaks AltGr characters on non-US layouts. Remove remaps on Ctrl/Alt or target only one side.
Most likely fix: Remove modifier remaps
How to fix it
// try these in order, the most common fix is first
FIX 1Remove modifier remaps
- 01Keyboard Manager > Remap a key
- 02Delete remaps of Ctrl or Alt and test AltGr
Did this fix it?FIX 2Remap only the side you need
- 01Use Left or Right variants instead of the generic Ctrl/Alt key
Did this fix it?FIX 3Use a shortcut remap instead of a key remap
- 01Remap a specific shortcut so the modifier itself stays untouched
Did this fix it?
Symptoms
After remapping, characters like @, € or { on AltGr layouts stop typing, or touchpad gestures stop working.
Why it happens
- C-01AltGr is treated as LCtrl+RAlt by Windows
- C-02Remapping Win/Ctrl/Alt/Shift breaks gestures and special keys (known issue #3703)
- C-03Office or Copilot keys actually send shortcuts
